3
Check the STO circuit connections based on the circuit diagram.
4
Check that the shield of the STO input cable is grounded to the drive
frame.
5
Close the disconnector and switch the power supply on.
5.1
Test the STO signal #1 when the motor stops:
Set STO1 and STO2 to "H".
Send a stop command to the drive (if running) and wait until the
motor shaft is at standstill.
Awake the STO function by de‑energizing (low state or open‑circuit)
the STO input signal #1 and send a start command to the drive.
Ensure that the motor stays at a standstill and the keypad of the drive
displays "E150.1".
5.2
Set STO1 to "H" and disable the ON/RUN command of the drive.
Then, reset the drive automatically and enable ON/RUN command of
the drive. Finally, check whether the motor runs normally.
5.3
Test the STO signal #2 when the motor stops:
Set STO1 and STO2 to "H".
Send a stop command to the drive (if running) and wait until the
motor shaft is at standstill.
Awake the STO function by de‑energizing (low state or open‑circuit)
the STO input signal 2 and send a start command to the drive.
Ensure that the motor stays at a standstill and the keypad of the drive
displays "E150.1".
5.4
Set STO2 to "H" and disable the ON/RUN command of the drive.
Then, reset the drive automatically and enable ON/RUN command of
the drive. Finally, check whether the motor runs normally.
6.1
Test the STO channel 1 when the motor is running:
Set STO1 and STO2 to "H".
Start the drive and ensure the motor is running.
Awake the STO function by de‑energizing (low state or open‑circuit)
the STO input signal 1.
Ensure that the motor stops and the drive trips.
Reset the fault and try to start the drive.
Ensure that the motor stays at a standstill and the keypad of the drive
displays "E150.1".
6.2
Set STO1 to "H" and disable the ON/RUN command of the drive.
Then, reset the drive automatically and enable ON/RUN command of
the drive. Finally, check whether the motor runs normally.
