7.6.8 Setpoint changeover (hand/remote changeover)
Description
Changeover between the setpoints NSET1−N1 and NSET1−N2.
·
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.
·
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.
Activation
Analog setpoint changeover via analog input
·
The setpoint source for remote operation must be linked with NSET1−N1 under C0412/1.
·
The setpoint source for manual operation must be linked with NSET1−N2 under C0412/2.
·
A digital input signal must be linked with the manual/remote changeover (DCTRL1−H/Re)
under C0410/17.
·
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.
Example
·
Invert X3/E6 with C0411 = 32.
·
Assign X3/E6 to the subcode C0410/17 with C0410/17 = 6.
·
The setpoint can be selected under C0044 using the keypad or PC.
·
If C0411 = 0 is set, the remote operation is active again.
Influence on other setpoints
·
JOG frequency are not effected by a manual/remote changeover.
·
Function
j of the keypad E82ZBC simultaneously acts on NSET1−N1 and NSET−N2.
– Use C0046 (NSET1−N1) and C0044 (NSET1−N2) for separated setpoint selection.
