Value Function Description Signal
71 Motorpot.F+ & Save ³
SW 1.6 and above
Motor potentiometer function frequency +/- with automatic saving, with this
motor pot. function (SW 1.6 and above) a setpoint value (sum) is set via the
digital inputs, which is 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 value can also be displayed or set in the operating value
display (P001=30, actual setpoint MP-S) or in P718 and can be preset in the
"Standby" operating mode.
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.

1 If neither of the digital inputs is programmed for left or right enable, then the actuation of a fixed frequency or jog frequency will enable the frequency
inverter. The rotation field direction depends on the sign of the setpoint.
2 Also effective for Bus control (z.B. RS232, RS485, CANbus, CANopen, …)
3 With SK 5x5 E devices the frequency inverter control unit must be supplied with power for a further 5 minutes after the last change of the motor
potentiometer in order to permanently save the data.
4 Function cannot be selected via BUS IO In Bits

HTL encoder function (only DIN2/4 )
For the evaluation of an HTL encoder, the digital inputs DIN2 and DIN4 must be parameterised with
the following functions.

This function
can only be
used for digital
inputs 2 (DIN2)
and 4 (DIN4)
!
A 24V HTL encoder can be connected to DIN 2 and DIN 4 in order to
measure the speed. The maximum frequency at the DIN is limited to
10kHz. Accordingly, a suitable encoder (low pulse number) or
suitable mounting (slow speed) SHOULD BE USED.
The direction of counting can be changed by exchanging the
functions on the digital inputs.
Further settings are in P461, P462, P463.

Setting of the stop time for the fast stop function which can be triggered either via a digital input,
the bus control, the keyboard or automatically in case of a fault.
Emergency stop time is the time for the linear frequency decrease from the set maximum
frequency (P105) to 0Hz. If an actual setpoint <100% is being used, the emergency stop time is
reduced correspondingly.
