Danger!
When operating the motor with a rotary encoder, the line to the motor must be connected on the motor
and inverter side phase-correct: U -> U / V -> V / W -> W.
Never swap the connection; not even if the rotary direction of the motor is false!! If the motor phases
are swapped, motor control is generally not possible. This can lead to jerky movements or uncontrolled
acceleration of the motor.

5.10.5 Electronic short-circuit
If emergency evacuation is performed by opening the brakes, the motor windings are short-circuited
by a self-activating electronic short-circuit to prevent uncontrolled acceleration of the lift. The short-
circuit generates a speed-dependent brake torque which is suf
fi
cient in most cases to limit the lift
speed to a safe value.
Information
•
The electronic short-circuit is also active when there is no operating voltage on the ZAdyn4C.
•
If a ZAdyn4CS with an integrated electronic short-circuit is switched to an asynchronous motor, the
electronic short-circuit can no longer be triggered.
•
The electronic short-circuit must be deactivated when checking the weight balancing by opening the
brakes.
• Please contact Ziehl-Abegg if you want to switch off the electronic short-circuit.
CAUTION!
When operating synchronous motors from other manufacturers, make sure that they can be operated
with the electronic short-circuit and that manual emergency evacuation with short-circuited motor
windings is permissible.
5.11 Motor temperature monitoring (X-MT)
Information
The detection of over temperature of the motor doesn't cause a drive interruption. The current drive
will be completed.
If an over temperature of the motor will be detected at stop, there is no further drive possible.
The following sensor types can be used:
•
PTC thermistor (PTC in compliance with DIN 44082, switching point at 3500
Ω
)
•
Temperature sensor KTY84-130 (switching point adjustable: Parameter
Monitoring/R_P1P2
)
•
Thermal circuit breaker
The used sensor has to be parametrized in the menue
