11-6-2. ERC signal
A servomotor delays the stop until the deflection counter in the driver reaches zero, even after command
pulses have stopped being delivered. In order to stop the servomotor immediately, the deflection counter
in the servo driver must be cleared.
This LSI can output a signal to clear the deflection counter in the servo driver. This signal is referred to
as an "ERC signal." The ERC signal is output as one shot signal or a logic level signal. The output type
can be selected by setting the RENV1 register (environment setting 1). If an interval is required for the
servo driver to recover after turning OFF the ERC signal (HIGH) before it can receive new command
pulses, the ERC signal OFF timer can be selected by setting the RENV1 register.
In order to output an ERC signal at the completion of a zero return operation, set EROR (bit 11) = 1 in
the RENV1 register (environment setting 1) to make the ERC signal an automatic output. For details
about ERC signal output timing, see the timing waveform in section 9-5-1, "Zero return operation."
In order to output an ERC signal for an immediate stop based on the EL signal, ALM signal, or
signal input, or on the emergency stop command (05h), set EROE (bit 10) = 1 in the RENV1 register,
and set automatic output for the ERC signal. (In the case of a deceleration stop, the ERC signal cannot
be output, even when set for automatic output.)
The ERC signal can be output by writing an ERC output command (24h).
The output logic of the ERC signal can be changed by setting the RENV1 register. Read the RSTS
(extension status) register to monitor the ERC signal.
