9 Safety function during the adjustment
• In active setting mode, the safety functions and fault monitor are active.
• If the operating voltage is interrupted during setting mode or no keys are pressed for ≥ 20 s,
setting mode is ended without saving the new values.
• The previous parameters remain effective.
• New parameters must be saved to become effective.
Faults monitoring
Faults display
• While the standstill monitor is in operation, it
continuously monitors for internal and external
faults. LED b8 flashes red (picture 4) if:
‒ Wire breakage in the measurement circuit.
‒ Inconsistent signals at the single phases
‒ Not allowed connection of the control inputs
I11/I22
‒ Power supply out of the tolerance range
‒ Internal unit faults
• The fault monitor is always active.
• In the event of a fault, the output contacts are
switched off.

After an external fault is corrected,
normal operation resumes.
If there were internal faults the unit
has to be returned to the
manufacturer.

9.1 Monitoring the protective equipment
Operating mode FA1
Diagram 3a
In order to monitor the protective equipment, inputs I11 and I22 are disconnected.
Accordingly, the standstill monitor is constantly active.
Contacts 13
-14/ 23-24 (serial circuit) are used to control the interlock of the protective
equipment. The contacts only close when the system drive is at a standstill. Then, the
protective equipment is unlocked.

9.2 Standstill monitoring
Operating mode FA2
Diagram 3b
In order to monitor the standstill, inputs I11 and I2 are controlled with 24V DC using the
switch of the protective equipment.
In automatic mode
(protective equipment closed), the monitor is inactive.
Relay contacts 13
-14 and 23-24 are permanently closed and the STOP LED lights up green.
Opening the protective hood initiates a change to FA1 mode.
Movement of the drive triggers the emergency stop function.

NOTE
The user must set the switching threshold (EMF limit) and the ON delay time (T) to ensure
that the relays K1 and K2 switch only at the standstill of the motor.
