6. Commissioning
instructions
For quick setup and trouble-free operation of the ERS the following procedure is recommended when
commissioning.
1. If
it is in an existing plant and a brake chopper is used, it is recommended that the voltage across
the resistor is looked at with a suitable instrument (Multimeter, oscilloscope, etc.).
Based on the maximum operating voltage you can make the default setting of thresholds (sec. 3.4.) at
the ERS. Alternatively, the switching thresholds of the brake chopper can be taken from the technical
documentation or requested of the device manufacturer of the frequency inverter or servo drive.
2. Switch the controller without voltage
3. Connect the ERS to the DC link terminals of the inverter or the servo controller (e.g. sec. 4.3. / 4.4.).
To comply with EMC, it is advisable to use a shielded cable and the shielding on both sides.
!!! IMPORTANT: Please note the polarity of the DC link voltage. It is NOT a polarity protection in
the ERS integrated
4. Connect the ERS with the 3-phase supply network
!!! IMPORTANT: The operation of the ERS is only possible on a CLOCKWISE ROTATING
FIELD!!!!!!
5.
If necessary, connect the inputs / outputs of the ERS with your application.
!!! RECOMMENDATION: During the initial commissioning it is recommended that the enable
input (sec. 5.1.) when switching on the controller is not set to!!!!!!
6. Switch on the controller
7.
After a moment, a visual indicator appears in the ERS (sec. 8.)
8. If network synchronization was successful and no other error is displayed, "Enable" can be set.
This is indicated by visual display (sec.8.)
9. Subsequently, a test run can be performed
!!! INFO: The feedback operation of the ERS is visually displayed (sec. 8.)!!!
!!!TIP: Set the switching thresholds so that the brake chopper is used as little as possible or
not at all in normal mode!!!
!!! IMPORTANT: Please note that the feedback mode is possible only with existing 3-phase
voltage. If during the regenerative operation or shortly before it comes to a fault, it is
recommended to provide a braking resistor for emergency braking!!!
