Value Function Description Signal
67 Dig. output man/auto set
“Set digital output manually /
automatically”
Set digital output 1 manually or via the set function in (P434).
High
68 Digital output. man set
“Set digital output manually”
Set digital output 1 manually

69 Speed measurement with ini.
“Speed measurement with initiator”
Simple speed measurement (pulse measurement) with initiator
pulses
70 Evacuation run
“Activate evacuation run”
This provides the option of operation with a very low link circuit
voltage (e.g. from batteries). With this function the charging
relay is actuated and the existing monitoring functions are
disabled.
NOTICE! No overload monitoring! (E.g. lifting equipment)

Motorpot.F+ and Save
“Motor potentiometer function
Fre with automatic saving".
With this “motor pot. Function” a setpoint (value) is set and
saved via the digital inputs. With R/L by the controller, this is
then started up in the correspondingly enabled direction. The
frequency is retained if the direction is changed.
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
can be displayed or set in P718.
A minimum frequency which is set (P104) remains effective.
Other setpoint values, e.g. analog or fixed frequencies can be
added or subtracted.
Adjustment of the frequency setpoint is performed with the
ramps from P102/103.

79 Rotor pos. ident. Precise knowledge of the rotor position is essential for PMSM
operation. Rotor position identification is performed if the
following conditions are met:
• The frequency inverter is in the status “ready for switch-on”,
• The rotor position is not known (see P434, P481, function
“28”),
• Function “2” is selected in P336.

1 If no digital input is parameterised for “enable right” or “enable left”, and for devices SK 270E-FDS and higher, all BUS In bits
(P480) which are relevant for AS-i are deactivated, a fixed frequency or the jog frequency results in enabling of the frequency
inverter. The direction of rotation depends on the prefix of the setpoint.
2 Also effective for control via BUS (e.g. RS232, RS485, CANopen, AS Interface, …)
3 For devices without an integrated low voltage unit (integrated low voltage unit: Option “-HVS“), the control unit of the frequency
inverter must be supplied with power for at least 5 minutes after the last motor potentiometer change in order to permanently
save the data.
4 Function cannot be selected via BUS IO In Bits
