5.140.1 Setpoint path
• The signals in the setpoint path are limited to ±200.00 % of the motor Motor reference speed
(C00011).
• The signal at dnSpeedSetpointIn_n is first led via the function "Selection of fixed setpoints".
• A selected fixed setpoint switches the input dnSpeedSetpointIn_n inactive and the subsequent
signal conditioning uses the selected fixed setpoint.
• By setting the input bInvertSetpoint to TRUE the input signal of the ramp generator can be in-
verted.
5.140.2 Fixed setpoints
In addition to the direct setpoint selection via the input dnSpeedSetpointIn_n fixed setpoints can be
preset in C04200/1...15.
• These fixed setpoints can be called binary coded any time via the selection inputs bJog1 ... bJog8,
so 15 options are available.
• The number of selected inputs to be assigned depends on the number of required fixed set-
points.
