Siemens SINAMICS G120C DP User Manual

Example
After it has been switched on, a conveyor belt only runs with two di󹪜erent velocities. The motor
should now operate with the following corresponding speeds:
• The signal at digital input0 switches the motor on and accelerates it up to 300rpm.
• The signal at digital input1 accelerates the motor up to 2000rpm.
• With signals at both digital inputs, the motor accelerates up to 2300 rpm.

300.000
Fixed speed setpoint 1
p1002[0] =
2000.000
Fixed speed setpoint 2
p0840[0] = 722.0 ON/OFF1: Switches on the motor with digital input0
p1070[0] = 1024 Main setpoint: Interconnects the main setpoint with a 󹪝xed speed setpoint.
p1020[0] = 722.0 Fixed speed setpoint selection bit 0: Interconnects 󹪝xed speed setpoint 1 with dig‐
ital input0 (DI0).
p1021[0] = 722.1 Fixed speed setpoint selection bit 1: Interconnects 󹪝xed speed setpoint 2 with dig‐
ital input1 (DI1).
p1016 = 1 Fixed speed setpoint mode: Directly selects 󹪝xed speed setpoints.
