BUS-In bits (P480) are deactivated and DIP switches S1 "3- 5" are in the factory setting, the actuation of a fixed frequency or
the jog frequency leads to the enabling of the variable frequency drive. The rotation field direction depends on the sign of the
setpoint.
2 Also effective for BUS control (e.g. RS232, RS485, CANopen, AS-Interface, ...)

Description
Set digital output 1 manually, or via the function set in (P434)
output
Set digital output 1 manually
Simple speed measurement (impulse measurement) with initiator
This also provides the possibility of operation with a very low DC
link voltage (e.g. using batteries). With this function the charging
relay is activated and existing monitoring functions are
deactivated.
CAUTION! There is no overload monitoring! (e.g. lifting gear)
With this "motor potentiometer function" a setpoint (sum) is set
via the digital inputs, and simultaneously stored. With control
enabling R/L this is then started up in the correspondingly
enabled direction. On change of direction the frequency is
retained.
Simultaneous activation of the +/- function causes the frequency
setpoint value to be set to zero.
The frequency setpoint can also be displayed or set in the
operating value display (P001 = 30, "Cur. set value MP-S") or in
P718.
Any minimum frequency set (P104) is still effective. Other
setpoint values, e.g. analog or fixed frequencies, can be added or
subtracted.
The adjustment of the frequency setpoint value is performed with
the ramps from P102/103.

Exact knowledge of the rotor position is essential for PMSM
operation. Rotor position identification is performed if the
following conditions are met:
• The variable frequency drive is in the status "ready to switch-
on",
• The rotor position is not known (see P434, P481, function
"28"),
• Function "2" is selected in P336.
The program execution of the integrated PLC is stopped for as
long as the signal is present.
