10.8.8 Setpoint changeover (hand/remote changeover)
Changeover between the setpoints NSET1-N1 and NSET1-N2.
l With manual/remote changeover it is possible to e.g. change from remote
operation to manual operation in the event of setting or service at the drive.
– For manual operation the setpoint source for remote operation must not
be changed.
– In manual operation the setpoint is selected via potentiometer, motor
potentiometer or keypad/PC.
l Examples for setpoint changeovers:
– Bus operation
ó Keypad or PC
– Bus operation
ó analog setpoint via analog input
– Keypad or PC
ó analog setpoint via analog input
– Function “Motor potentiometer”
ó analog setpoint via analog input
– Analog setpoint via analog input
ó setpoint via frequency input
– Analog input 1
ó analog input 2 (application I/O only)

) Note!
The safety functions controller inhibit and quick stop (QSP) set in
remote operation will be reset when manual operation is being
activated. Check whether the master system reactivates these
functions after a changeover.
Analog setpoint changeover via analog input
l The setpoint source for remote operation must be linked with NSET1-N1
under C0412/1.
l The setpoint source for manual operation must be linked with NSET1-N2
under C0412/2.
l A digital input signal must be linked with the manual/remote changeover
(DCTRL1-H/Re) under C0410/17.
l HIGH active inputs:
– Manual operation active if signal source for DCTRL1-H/Re = HIGH
Activation of ”bus operation
ó keypad or PC”
1. Internally invert a digital input (X3/E5 or X3/E6) not used in the Lenze setting
under C0411.
2. Assign this input C0410/17 (DCTRL1-H/Re) to activate manual operation.
3. If the inversion of the digital input reset (C0411 = 0), remote operation will be
active again.
