5.4.3 Internal output circuit

The signal state represents the "ON: Carrying current" or "OFF: Not carrying current" state of the internal
photocoupler rather than the voltage level of the signal.

±CW-P (±PULSE) output, ±CCW-P (±DIR) output
These terminals are used to output pulses.
Information in parentheses is for 1-pulse output mode. In the 1-pulse output mode, the motor will
rotate in the CW direction with the DIR output turned on and in the CCW direction with the DIR output
turned off.
The output mode may be switched between 1-pulse and 2-pulse modes via the PULSE command.
(Set to "2-pulse mode" at the time of power-on.)
±CCR output
These terminals are used to output counter clear signals for resetting the counter in the driver.
These terminals should be connected when a servo motor is used.
The circuit will generate CCR outputs in any of the following situations (output width 500µs):
• The E-STOP input is turned off while the motor is in operation
• While mechanical home seeking is in progress
• When the motor has pulled out from the limit sensor during continuous operation
• When an alarm event has caused the operation to stop immediately
• When the power is turned on or the RESET command is input
