B-3-2 DS402 Standard Control Mode
B-3-2-1 Related set up for an AC motor drive (following the DS402 standard)
If you want to use the DS402 standard to control the motor drive, follow these steps:
1. Wire the hardware (refer to chapter B-2 Wiring for CANopen).
2. Set the operation source: set Pr.01-01 to 3 for CANopen communication card control.
3. Set the frequency source: set Pr.03-15 to 6. Choose the source for the Frequency command
from the CANopen setting.
4. Set DS402 for the control mode: Pr.04-20=1
5. Set the CANopen station: set the CANopen station (range 1-127, 0 is the disable CANopen
slave function) with Pr.04-17. Note: set Pr.00-02 = 7 to reset if the station number error
CAdE or CANopen memory error CFrE appears.
6. Set the CANopen baud rate: set Pr.04-18 (CANBUS Baud Rate: 1M (0), 500K (1), 250K (2),
125K (3), 100K (4) or 50K (5)).
B-3-2-2 The status of the motor drive (by following DS402 standard)
According to the DS402 definition, the motor drive is divided into 3 blocks and 9 statuses as
described below.
3 blocks
1. Power Disable: without PWM output
2. Power Enable: with PWM output
3. Fault: one or more errors have occurred.
9 status
1. Start: power on
2. Not Ready to Switch On: the motor drive is initiating.
3. Switch On Disable: occurs when the motor drive finishes initiating.
4. Ready to Switch On: warming up before running.
5. Switch On: the motor drive has the PWM output, but the reference command is not
effective.
6. Operate Enable: able to control normally.
7. Quick Stop Active: when there is a Quick Stop request, stop running the motor
drive.
8. Fault Reaction Active: the motor drive detects conditions which might trigger error(s).
9. Fault: one or more errors have occurred in the motor drive.
