NORDAC FLEX (SK 200E ... SK 235E) – Users Manual for Frequency Inverters
Value Function
If the drive is to start up automatically when the mains is switched on (P428 = 1) a permanent High level for
enabling must be provided (supply terminal 21 with 24V).
If the functions "Enable right" and "Enable left" are actuated simultaneously, the FI is blocked.
If the frequency inverter is in fault status but the cause of the fault no longer exists, the error message is
acknowledged with a 1 → 0 flank.

If several fixed frequencies are actuated at the same time, then they are added with the correct sign. In
addition, the analogue setpoint (P400) and if necessary the minimum frequency (P104) are added.

Description
Causes the rotation field to change direction in combination with
Enable right or left.
The frequency from P465 [01] is added to the actual setpoint
value.
The frequency from P465 [02] is added to the actual setpoint
value.
The frequency from P465 [03] is added to the actual setpoint
value.
The frequency from P465 [04] is added to the actual setpoint
value.
Selection of active parameter set 1...4 - first bit.
During the acceleration or deceleration phase, a Low level will
cause the actual output frequency to be "Held". A High level
allows the ramp to proceed.
The FI output voltage is switched off; the motor runs down freely.
The FI reduces the frequency according to the programmed fast
stop time P426.
Fault acknowledgement with an external signal. If this function is
not programmed, a fault can also be acknowledged by a low
enable setting (P506).
Only with the use of a temperature monitor (bimetallic switching
contact). Switch-off delay = 2sec, warning after 1 sec.
With bus system control, Low level switches the control to control
via control terminals.
The frequency value from (P113) can also be set directly using
the HIGHER/LOWER buttons with a controller, SimpleBox or
ParameterBox and stored in (P113) using the OK button.
If the device is operating with inching frequency, any bus
actuation that may be active is deactivated.
As in setting 09, however, the frequency is not maintained below
the minimum frequency P104 and above the maximum frequency
P105.
Selection of active parameter set 1...4 - second bit.
Input must see a High flank cyclically (P460), otherwise error
E012 will cause a shutdown. Function starts with the 1st high
flank.
SK 2x0E: Analogue input switch-on and switch-off 1/2 (high =
ON) of the frequency inverter
SK 2x5E: Analogue input switch-on and switch-off 1/2 (high =
ON) of the first I/O extension. The Low signal sets the analogue
input to 0 % which does not lead to shutdown when the minimum
frequency (P104) > than the absolute minimum frequency (P505).
