Group 3 Parameter Descriptions
Group 3.1 - System - System Mechanical Data/Linear Units operation
Parameter Number | Parameter Name | Units | Default | Available Settings | Access | Change During Run | Scaling | Size (Bytes) | CAN Register | CAN Sub Index | Modbus Register |
|---|---|---|---|---|---|---|---|---|---|---|---|
P3-01 | Motor Contactor Closing Time | sec | 0.2s | 0.0 ... 5.0s | RW | Y | 1 = 0.1s | 1 | 212Dh | 0 | 301 |
Sets a delay time between a Direction signal being applied to the drive and the drive energising the motor, this ensures that the motor contactor has had enough time to change state before current flows from the drive to the motor.
Typical values are 0.2 to 0.5 seconds.
During the delay time the drive will display “CC”. When the display shows CC this means the motor contactor is closing.
Group 3.2 - System - Motor Contactor Monitoring
Parameter Number | Parameter Name | Units | Default | Available Settings | Access | Change During Run | Scaling | Size (Bytes) | CAN Register | CAN Sub Index | Modbus Register |
|---|---|---|---|---|---|---|---|---|---|---|---|
P3-02 | Motor Contactor Monitoring Terminal Enable | N/A | 0: Off | 0: Off 1: Enabled | RW | Y | N/A | 1 | 212Eh | 0 | 302 |
P3-03 | Total Number of Motor Contactor Monitoring Errors | N/A | 0 | 0 ... 65535 | RO | N/A | N/A | 2 | 212Fh | 0 | 303 |
Sets the Motor Contactor Monitoring function to enabled or disabled.
Setting | Function |
|---|---|
0 | Off - Motor Contactor Monitoring disabled |
1 | Enabled - Motor Contactor Monitoring enabled |
Applicable Macros (P1-02) for Motor Contactor Monitoring Function:
This value increases by 1 each time there is CF-Err error.
The value can only be reset to 0 by loading factory/user defaults.
Group 3.3 - System - Brake Resistor Protection
Parameter Number | Parameter Name | Units | Default | Available Settings | Access | Change During Run | Scaling | Size (Bytes) | CAN Register | CAN Sub Index | Modbus Register |
|---|---|---|---|---|---|---|---|---|---|---|---|
P3-04 | Brake Resistor Resistance | ohms | Rating Dependent | 0 ... 60000 ohms | RW | Y | N/A | 2 | 2130h | 0 | 304 |
P3-05 | Brake Resistor Power | kW | 0.0kW | 0.0 ... 6000.0 kW | RW | Y | 1 = 1W | 2 | 2131h | 0 | 305 |
P3-06 | Brake Resistor Temperature Monitor Enable | N/A | 0: Disabled | 0: Disabled 1: Enabled | RW | Y | N/A | 1 | 2132h | 0 | 306 |
P3-07 | Brake Resistor Temperature Monitoring trip reaction | N/A | 0 : Normal Stop, Trip After stopping | 0: Normal Stop, Trip After stopping 1 : Immediate Trip, Apply motor Brake 2: Warning Only No Trip | RW | Y | N/A | 1 | 2133h | 0 | 307 |
Enter external Brake Resistor resistance in ohms.
For software protection of the connected brake resistor, enter the rated power and resistance of the resistor into the relevant parameters. The drive will then monitor the brake resistor to ensure that it does not operate outside of its designed limits. Where an external thermal protection device is fitted, and software protection is not required. Setting parameter P3-05 to zero will disable the software protection feature.
This parameter is used when a brake resistor thermal switch is wired back to a Digital Input set for External Trip and tells the drive that the drive should trip on a brake resistor feedback fault (Ot-br)rather than an external trip.
This parameter defines the drive’s reaction when the Brake Resistor Overload function has been triggered (Ot-br)
Setting | Function | Reaction Details |
|---|---|---|
0 | Stop then Trip | Drive stops normally then trips |
1 | Trip Immediately | Immediate trip, apply motor brake |
2 | Warning Only | Warning only, no trip. |
Group 3.4 - System - System Mechanical Data/Linear Units operation
Parameter Number | Parameter Name | Units | Default | Available Settings | Access | Change During Run | Scaling | Size (Bytes) | CAN Register | CAN Sub Index | Modbus Register |
|---|---|---|---|---|---|---|---|---|---|---|---|
P3-08 | Sheave Diameter | N/A | 0.0 | 0.0 ... 2000.0 | RW | Y | 1 = 0.1 | 2 | 2134h | 0 | 308 |
P3-09 | Roping Ratio | N/A | 1: 1:1 | 1: 1:1 2: 2:1 3: 3:1 4: 4:1 | RW | Y | N/A | 1 | 2135h | 0 | 309 |
P3-10 | Gear Ratio | N/A | 1.0 | 1.0 ... 100.0 | RW | Y | 10 = 1.0 | 2 | 2136h | 0 | 310 |
P3-12 | System Inertia Constant | N/A | 10 | 0 ... 100 | RW | Y | N/A | 1 | 2138h | 0 | 312 |
This defines the traction sheave diameter. If the entered value in P3-08 is <100 drive assumes inches and if the value entered in >=100 the drive assumes mm.
This defines the roping ratio of the system.
Setting | Roping Ratio |
|---|---|
1 | 1:1 |
2 | 2:1 |
3 | 3:1 |
4 | 4:1 |
This defines the Gear Ratio of the mechanical Gear.
This value can normally be left at the default value (10).
