Warning
If the current set is too large for the motor, the motor might be damaged due to
overtemperature.
Start-up sequence
1. Connect the mains voltage and - if necessary - also the 24 V supply
voltage.
2. Check the DIS LED.
3. Activate the ENABLE signal via the control system (power-up the control
system).
The yellow DIS LED goes out and the green RDY LED is lit. The drive is ready,
the motor is powered.
If the PULSE signal is provided by the control system with pulses, then motor
will rotate in the direction of rotation specified by the DIR signal.
Notice
The DIR switch can be used to adapt the direction of rotation to the mechanics
of the machine. Never actuate the switch when the drive is powered!
