Notifying the timing of electromagnetic brake control: MBC output
Use the MBC output to control the electromagnetic brake using a programmable controller, etc.
The MBC output can be enabled by selecting the output using the application parameter for output signal
selection 1 [APP-1-02].
The MBC output will turn ON when the electromagnetic brake is released, and turn OFF when the
electromagnetic brake is actuated (= to hold the load in position). Set the programmable controller to control
the electromagnetic brake by detecting the ON/OFF status of the MBC output.

Clear the accumulated pulses (deviation) to zero: CLR input
When the CLR input is turned ON, the pulses accumulated in the deviation counter (= deviation) will be
cleared to zero.
Input pulses are ignored while the CLR input is ON.

Note
• The CLR input functions as the P-CK input when the P-REQ input is ON. Accordingly,
turning the CLR input ON while the P-REQ input is ON will not clear the deviation
counter.
• When an alarm generates, the CLR input changes to ALM-RST input. Take note that
when the P-REQ input is ON, the function of the P-CK input is given priority and
therefore turning ON the ALM-RST input will not reset the alarm.

Presetting the current position: P-PRESET input
When the P-PRESET input is turned ON, the value in the application parameter for preset value [APP-1-09]
will be overwritten by the current position and the current position will become the home position.
If the absolute function is enabled, turning the P-PRESET input ON will set the home position. The preset
value will be written to the EEPROM.
If the absolute function is disabled, the preset value is not written to the EEPROM. Accordingly, cycling the
power will reset the current position to zero.
If a current position loss alarm has generated, perform a return-to-home operation after resetting the alarm,
and then set the home position using the P-PRESET input.

Note
• The EEPROM can be rewritten approx. 100,000 times.
• Do not turn off the main power and 24 VDC power for at least 5 seconds after the
P-PRESET input has turned ON. If the power is turned off within 5 seconds, the preset
value may not be reflected properly.
