SW 1.7 and above Only for devices with external 24V control voltage (SK 5x5E). There is therefore
also the possibility of operation with a very low link circuit voltage. With this
function the charging relay is activated and the undervoltage and phase error
detection are deactivated.
CAUTION! There is no overload monitoring! (e.g. lifting gear)

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

Pulse input functions: 2...22kHz (only DIN2/3)
Digital inputs 2 and 3 can be used indirectly for the evaluation of analog signals. For these functions
the particular input evaluates the impulse frequency present. The frequency range 2kHz to 22kHz
thereby covers the range of values from 0 to 100%. The inputs operate up to a maximum impulse
frequency of 32kHz. The voltage level may be between 15V and 24V and the switch-on cycle between
50 and 80%.
