2.2 Restrictions on Combinations of Units
2.2.1 Unit Combinations for Positioning Control
■
Interfaces provided with the pulse output unit
● In addition to pulse command output for the motor driver, the pulse output unit is equipped
with the following inputs and outputs.
Home input
Near home input
Over limit input (+)
Over limit input (-)
Positioning control start input (timing input) for JOG positioning operation
Servo ON output for the servo amplifier
Deviation counter clear output
● For PLC safety circuit and control signal interfaces, use I/O connectors of the GM1 Controller
and other expansion units in combination.
■
Counting the number of output pulses
The number of pulses output is counted as an absolute value by an internal counter inside the
pulse output unit, which counts them as the "elapsed value".
Counting range: -2,147,483,648 to +2,147,483,647 (signed 32-bit)
■
Counting the number of input pulses from the external encoder
The number of pulses input is counted as an absolute value by an internal counter inside the
pulse output unit, which counts them as the "feedback count value".
Counting range: -2,147,483,648 to +2,147,483,647 (signed 32-bit)
● If the "elapsed value" or "feedback count value" exceeds the maximum / minimum value, the
value returns automatically to the minimum / maximum value and counting continues from that
point.
● The motor does not stop if this occurs, and no error occurs.
