Connection of control signals to the drive controller 712

Fig. 7 Connection of setpoint signals and the controller enable
The device can evaluate a setpoint signal from a potentiometer or master
ƒ
voltage using terminals 7, 8 and 9. In addition, for winding applications a
second setpoint can be defined at terminals 12, 13 and 14 using a dancer
potentiometer.
The drive controller is enabled using an external contact to be connected
ƒ
to terminals 16 and 17. For this purpose a low current contact (10 V,
10 mA) is to be used.

Note!
Use suitable relay contacts if control signals are switched using a
relay.
The drive controller is enabled with switch RFR closed.
If RFR is opened, the enable pulse and the drive controller are reset.
