CHAPTER 2 WIRING
(2) ABS/INC (positioning data)
After the pause (“31”) signal is turned off, the remaining motion continues without relations to
the absolute (ABS) or incremental (INC) mode of positioning data.
This signal is irrelevant to the setting of the INC/ABS system selection parameter (PA1_02).
(3) Brake timing
2
The brake is not applied in a pause.
Positioning cancel: Sequence input signal (Reference value 32)
This signal is used to cancel the auto start, homing motion, and interrupt positioning motion on the way.
Function
To resume homing motion, turn on the positioning cancel signal and then turn on the homing
signal again.
The interrupt positioning motion cancels the interrupt positioning motion after interrupt input is
turned on.
This function is disabled for the pulse operation.
Unlike forced stop, controlled stop will be conducted within the selected deceleration time.
Parameter setting
To assign positioning cancel to a sequence input terminal, specify the corresponding value ("32")
to the input terminal function setting parameter.
External regenerative resistor overheat: Sequence input signal (Reference value 34)
The thermistor signal of the external regenerative resistor forcibly stops the servomotor.
Function
In a system where the regenerative power is relatively large, install an external regenerative
resistor and connect the resistor thermistor signal to the CONT signal assigned as an external
regenerative resistor overheat signal.
If the external regenerative resistor overheat input signal is turned on (switch:open), an external
regenerative resistor overheat (rH2) alarm is issued.
Parameter setting
To assign external regenerative resistor overheat to a sequence input terminal, specify the
corresponding value ("34") to the input terminal function setting parameter.
