Overview
Note
• Starting instruction: ACC(888) (continuous or independent), deceleration, absolute
The examples in this section demonstrate the functions with high-speed
counter 1 only. When using high-speed counter 2, replace the Auxiliary Area
addresses with the appropriate addresses for high-speed counter 2.
Either of the following types of pulse input signals can be input to the unit:
The following explains the functions that are compatible with the latter, Servo
Drivers compatible with absolute encoders.
Refer to 7-5 Pulse Inputs for details on pulse train inputs from devices such as
normal incremental encoders
To input the encoder output data from a Servo Driver compatible with an
absolute encoder, the SEN output signal from the Motion Control Module has
to be connected to the Servo Driver. When starting an operation, the number
of multi-turns (to phase A as serial data) and the initial incremental pulse (to
phase A/B as pulse) are input once as the absolute position information.
After that, the position data during operations are input with the phase differ-
ential input (using normal counter functions).
Using a Servo Driver compatible with an absolute encoder enables the con-
trolled operation to be started from the position at turning on the power with-
out performing any origin searches.
