Group 8 Parameter Descriptions
Group 8.1 - Travel Curve - Speed Limits
Parameter Number | Parameter Name | Units | Default | Available Settings | Access | Change During Run | Scaling | Size (Bytes) | CAN Register | CAN Sub Index | Modbus Register |
|---|---|---|---|---|---|---|---|---|---|---|---|
P8-01 | Maximum Frequency / Speed Limit | Hz / rpm / Linear | 50.00 | P8-02 ... 500.00 Hz | RW | N | 1 = 0.01Hz | 2 | 2321h | 0 | 801 |
P8-02 | Minimum Frequency / Speed Limit | Hz / rpm / Linear | 0.00 | 0.00 ... P8-01 | RW | N | 1 = 0.01Hz | 2 | 2322h | 0 | 802 |
Maximum output motor speed limit. If P4-06 (motor rated speed) > 0, the value entered / displayed is in Rpm. If System information has been entered into P3-08 (sheave diameter), P3-09 (roping ratio), P3-10(Gear ratio) then value entered/displayed will be in linear units. This parameter is updated automatically to match the values set in the motor rated frequency (P4-04) and motor rated speed (P4-06), the user can also set the value independently.
Minimum motor speed the drive will run at. The drive will always be clamped to this speed even if any speed reference parameters in Group 8 have a lower value than this parameter.
For example if P8-06 is selected as the speed reference and set to 25Hz while this parameter is set to 30Hz the drive will run at 30 Hz while P8-06 is the speed reference.
Group 8.2 - Travel Curve - Acceleration/Deceleration Ramp Times
Parameter Number | Parameter Name | Units | Default | Available Settings | Access | Change During Run | Scaling | Size (Bytes) | CAN Register | CAN Sub Index | Modbus Register |
|---|---|---|---|---|---|---|---|---|---|---|---|
P8-03 | Acceleration ramp time | sec | 2.00s | 0.00 ... 600.00s | RW | Y | 1 = 0.1s | 2 | 2323h | 0 | 803 |
P8-04 | Deceleration ramp time | sec | 2.00s | 0.00 ... 600.00s | RW | Y | 1 = 0.1s | 2 | 2324h | 0 | 804 |
Ramp used when accelerating to a speed from start.
The Jerks used during this are P9-01 and P9-02.
The total ramp time is calculated approximately: P8-03 + (P9-01 + P9-02 / 2).
Ramp used when decelerating to a speed reference >0.
The Jerks used during this ramp are P9-03 and P9-04.
The total ramp time is calculated approximately: P8-04 + (P9-03 + P9-04 / 2).

This parameter sets the speed reference for the drive to run at when levelling speed is selected. Levelling Speed can be selected via the Digital Inputs.
This parameter sets the speed reference for the drive to run at when High Speed is selected. High Speed can be selected via the Digital Inputs.
This parameter sets the speed reference for the drive to run at when Intermediate Speed is selected. Intermediate Speed can be selected via the Digital Inputs.
This parameter sets the speed reference for the drive to run at when Inspection Speed is selected. Inspection Speed can be selected via the Digital Inputs.
This parameter sets the speed reference for the drive to run at when High Speed 2 is selected. High Speed 2 can be selected via the Digital Inputs.
This parameter sets the speed reference for the drive to run at when High Speed 3 is selected. High Speed 3 can be selected via the Digital Inputs.
This parameter sets the speed reference for the drive to run at when High Speed 4 is selected. High Speed 4 can be selected via the Digital Inputs.
This parameter sets the speed reference for the drive to run at when High Speed 5 is selected. High Speed 5 can be selected via the Digital Inputs.
This parameter defines the stopping conditions for the Drive.
When set to 0 the stopping condition is direction command removed. If a zero speed reference is given the drive will stay enabled at zero speed until the direction command is removed.
When set to 1 an extra stopping condition is added. The stopping conditions become a direction removed OR a zero speed reference. This setting is used to stop the drive sitting at 0 speed for a prolonged period of time. For the zero speed reference condition to be fulfilled both the Pre-ramp and Post-ramp needs to be at 0 for at least 100ms.
Setting | Stopping Condition |
|---|---|
0 | Direction Input Removed |
1 | Direction Input Removed OR Zero Speed Reference |
