User Defined I/O - Customise Drive Starting & Speed Selection
When using the User Defined Macro (P1-02 = 0) there are a variety of direction and speed commands that can be used to control how the drive runs and customize the starting sequence of drive operation. This topic details the different type of direction and speed functions and how to set them up in the parameters.
When using Group 12 there are three different direction command options to select from:
Option 1 & Option 2 (Forward & Reverse)
Option 19 & Option 20 (Forward with Contactor Control & Reverse with Contactor Control)
Option 26 Direction (0 - Fwd, 1 - Rev)
Options 1 & 2 are standard Run forward and Run reverse commands that are used in all the standard settings of P1-02 except Macro 11. When using options 1 & 2 the assigned Digital Inputs just acts as a direction command with no other part of the sequence to consider.
When using Option 19 & Option 20 this allows the user to give a direction command as well as closing the motor contactor (if Relay 1 is assigned the motor contactor control function P1-30 = 11) when the Digital Input assigned either Option 19 or 20 is closed. This allows the motor contactor to be closed before the Safety Chain (terminals STO1 & STO2) is closed. When using these settings the drive can run with the Safety Chain being the last input to close.
When using Option 26 both directions are assigned to one Digital Input. When the Digital Input is open the drive will run forward and when closed the drive will run in reverse. The starting sequence in this option is the same as Options 1 & 2 where the motor contactor is not controlled via the direction command.
When using the drive the standard conditions to run are Direction, Speed and Safe Torque Off all need to be closed. However an extra condition can be added called Drive Enable and is used in Macro 9.
Macro 0 can be used to assign the drive enable function to any Digital Input. So an extra condition is needed to run and can be used to stop the drive when removed.
Function | Function Description | Group 12 Option Number | Available Terminals |
|---|---|---|---|
Drive Enable | Used as one of the conditions to run the drive. When assigned to a Digital Input that input must be closed before the drive can be run and if opened can be sued to stop the drive.
| 21: Drive Enable | All Digital Inputs |
Four different sets of speed references are available to program the speed reference of the drive. These can be selected using Macro 0 and are detailed below.
Speed Reference Type | Explanation | Group 12 Option Numbers |
|---|---|---|
Each single speed can be assigned to a individual Digital Input so that speed is selected when the Digital Input is closed. | 3 - Levelling Speed 4 - High Speed 5 - High Speed 5 6 - Inspection Speed | |
Each single speed can be assigned to a individual Digital Input so that speed is selected when the Digital Input is closed and when inputs are open a Preset Speed is used | 10: Preset with override High Speed 11: Preset with override Inspection Speed 12: Preset with override Intermediate Speed | |
This method uses up to 3 Digital Inputs each assigned a preset bit which will form a table which selects a speed depending on the state of the bits. | 14 - Preset Bit 0 15 - Preset Bit 1 16 - Preset Bit 2 | |
This method works the same ways as the Binary Speed Configuration, except the drive will not run unless at least one bit (Digital Input) is active. | 27 - Preset Bit 0 with Active 28 - Preset Bit 1 with Active 29 - Preset Bit 2 with Active |
This section details the available single speed parameters. The parameters listed use one Digital Input to select a speed. So for example Digital Input 1 can be assigned 3: Levelling Speed, so when Digital Input 1 is closed levelling speed is selected and when opened Digital Input 1 is disabled.
Note
If two or More Digital Inputs are closed at the same time the speed with the highest value takes priority as the speed reference.
Group 12 Option | Associated Parameter | Notes |
|---|---|---|
3 - Levelling Speed | P8-05 Levelling Speed | Use the associated parameters in Group 8 to set the speeds for the functions assigned to each Digital Input in Group 12. |
4 - High Speed | P8-06 High Speed | |
5 - High Speed 5 | P8-12 High Speed 5/Re-levelling Speed | |
6 - Inspection Speed | P8-08 Inspection Speed |
This section details the available single speed parameters as an override. The parameters listed use one Digital Input to select a speed. So for example Digital Input 1 can be assigned 10: Preset with override High Speed, so when Digital Input 1 is closed High Speed is selected and when opened leveling speed is used unless at least one of the other Digital Inputs are closed.
Note
If two or More Digital Inputs are closed at the same time the speed with the highest value takes priority as the speed reference.
Group 12 Option | Associated Parameter | Notes |
|---|---|---|
10: Preset with override High Speed | P8-05 Levelling Speed & P8-06 High Speed | These speed options work similar to the single speed selection options (Setting 3 - 6) where when a specific Digital Input is closed that speed reference is selected. However if none of the three Digital Inputs are closed then levelling speed is automatically selected as the speed reference. |
11: Preset with override Inspection Speed | P8-05 Levelling Speed & P8-07 Inspection Speed | |
12: Preset with override Intermediate Speed | P8-05 Levelling Speed & P8-08 Intermediate Speed |
The drive has 3 Preset bits available that when assigned to Digital Inputs form a truth table that selects the drives speed reference depending on the combination of the assigned digital input's state. The Preset bits can be selected using Options 10 - 12.
You can assign up to 3 Preset bits to Digital Inputs to act as the speed references , though the amount of available speeds will vary depending on the number of bits used:
1 Preset Bit = 2 Speeds
2 Preset Bits = 4 Speeds
3 Preset Bits = 8 Speeds
The tables show how using a combination of either 1, 2 or 3 Digital Inputs are assigned to each speed. Each Digital Input is assigned to a one of three preset bits (Preset Bit 0, 1 and 2).
1 Preset Bit | |

The drive has 3 Preset bits available that when assigned to Digital Inputs form a truth table that selects the drives speed reference depending on the combination of the assigned digital input's state. The Preset bits can be selected using Options 27 - 29.
Note
These option bits require at least one bit (Digital Input) to be active for the drive to run. If all three bits (Digital Inputs) are low the drive will not start.
You can assign up to 3 Preset bits to Digital Inputs to act as the speed references , though the amount of available speeds will vary depending on the number of bits used:
1 Preset Bit = 2 Speeds
2 Preset Bits = 4 Speeds
3 Preset Bits = 8 Speeds
