Description
2.1 General configuration
The ZF electronic control unit ERM can control ZF
hysteresis clutches and brakes in different operating
modes, as required by the application.
The ERM is controlled by a microprocessor and features
programming, operation and diagnosis interfaces.
The ERM is designed for optimum supply of the ZF
hysteresis clutches EKU and the ZF hysteresis brakes
EBU. Controlled operating modes with size coding are less
suitable for performance optimized brake range.
The DIL switches enable the following operating modes
to be set:
• Operating mode: "open-loop control (current)"
This operating mode is set by the manufacturer, i.e. it
is not necessary to change the DIL switch positions.
Current is set and kept constant in accordance with
the nominal value input.

Electronic control unit ERM
• Operating mode "open-loop control (torque)"
The DIL switches must be set to suit unit size
(Y Y Y Y) (see page 18).
Torque is set and kept constant in accordance with the
nominal value input.
Hereby, the interdependence of the nominal voltage
value/torque is subject to approximate linear distribution.

• Operating mode "controlled with Ø sensing"
The DIL switches must be set to suit unit size
(Y Y Y Y) (see page 18).
Setting procedure:
• sense maximum roller Ø
• push set key
• release set key
(reference value for max. Ø is accepted).
NOTE
Data are stored in non-volatile memory; data are not
erased when the supply voltage is switched off.
