1. Overview
This product is a pulse-train input type controller for actuators manufactured by IAI.
It allows controls according to the command signals from the positioning control function of a host
controller (PLC).
1.1 Features
Q
Dedicated Homing Signal
P-Driver supports our proprietary stroke end push homing operation. This function allows automatic
homing without using complex sequences or external sensors.
Q
Brake Control Function
The power supply of the electromagnetic brake is supplied to the controller, separately from the main
power supply. Since the brake is controlled by the controller, there is no need to program a sequence.
Moreover, the electromagnetic brake can be released at any point after the main power supply is cut off.
Q
Torque Limiting Function
The actuator torque can be limited using external signal (via parameter setting), and a signal is output
when the specified torque is reached. With the use of this function, push operation and press-fitting
become possible.
Q
Feed-Forward Control Function
Response can be raised under certain conditions, such as when the load inertial ratio is high.
Increasing this parameter setting decreases the deviation (difference between the position command
and the position feedback), thus resulting in improved response.
Q
Position-Command Primary Filter Function
Soft start and stop are possible even if acceleration/deceleration is not specified in the command pulse
input.
Q
Feedback Function
Position detection data can be output as pulse trains (differential output). This enables reading of the
current position in real time from the host controller.
