3 Product overview
3.1 Application
The ZAdyn4C MRL is a field-oriented frequency inverter for speed control of three-phase motors
developed for use in elevator machines.
They are based on the ZAdyn4C, whereby a brake control, a device switch, a brake resistance (except
ZAdyn4C MRL BE) and room for additional components (only ZAdyn4C MRL AI) have been addition-
ally integrated.
The inverter is equipped with a microprocessing control. This drives the motor based on time and
travel-dependent programs, which can be selected through the superordinate elevator controls. The
use of IGBT modules and a pulse width modulation in which the clock frequencies can be modified
enable low-noise motor operation. The user interface specifically matched to elevator technology,
interfaces and software enable simple installation and commissioning of the device.
The frequency inverter is designed for elevator installations for passenger and freight transport with a
high demand on travel comfort and positioning accuracy.
The frequency inverter has been developed for operating synchronous motors.
4 Mechanical installation

Before connecting to the mains, check if the technical data on the rating plate of the ZAdyn4C MRL
correspond to the required connection values.
5.6.1 Network form
The mains filter and ZAdyn4C MRL are designed for use in an earthed power supply system.
Permissible mains forms are:
•TN network
•TT network
Information
The mains filter and ZAdyn4C MRL are unsuitable for use in the IT network!
5.6.2 Cable cross section
The line cross-section must be specified dependent on the motor’s rated current and the ambient
conditions (e.g. temperature, wiring method) in accordance with DIN VDE 0100.
5.6.3 Mains fuse
The fuse protection is implemented in accordance with the line cross-section used.
5.6.4 Type of cable

5.7 Motor connection (X3)
5.7.1 Cable cross section
The line cross-section must be specified dependent on the motor´s current and the ambient conditions
(e.g. temperature, wiring method) in accordance with DIN VDE 0298-4.
5.7.2 Type of cable
Always use shielded cables for the motor connections! Both rigid and flexible lines can be installed.
The use of wire-end sleeves is recommended for flexible lines.
Rated voltage U0 / U: 450 / 750 VAC
5.7.3 Cable length
The maximum line length is 25 m. With a motor power line > 25 m compliance with DIN EN 12015
(electromagnetic compatibility – spurious emission and DIN EN 12016 (electromagnetic compatibility
– interference immunity) can no longer be guaranteed.
5.7.4 Connection
Danger!
Always switch off the mains voltage when connecting the motor line. The STO function (operation
without contactors) does not electrically isolate the output stage of the inverter from the motor line
terminal!
The motor connection is designed with spring contact terminals. To avoid damage to the connection
terminals and to ensure a safe contact, a suitable screwdriver must be inserted into the terminals as
far as it will go to fully open them when connecting cables.
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.

5.7.5 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 sufficient 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.
•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.
5.8 Motor temperature monitoring (X-MT)
Information
The X-MT terminal is a standard part of the ZAdyn4C MRL frequency inverter.
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 temperature monitoring is carried out according to IEC 61800-5-1:2003-02 (switching point at
3500 Ω)
The following sensor types can be used:
•PTC thermistor (PTC according to DIN 44082)
•Temperature sensor KTY84-130
•Thermal circuit breaker
The used sensor has to be parametrized in the menueMonitoring/P1P2!
