CHAPTER 4 PARAMETER
4-8
Basic Parameters
4
<Notes regarding operations>
1) The positioning command range when the absolute system position command format is
selected is;
2) The positioning command range when the incremental system position command format is
selected is;
3) Do not apply the immediate value continuation operation.
If applied, the positioning after continuation will rely on the calculation timing if operation is shifted
to continuous motion around the time when the multi-turn data is about to overflow.
4) Do not apply the immediate value change function.
When using the absolute position system, refer to "CHAPTER 11 ABSOLUTE POSITION
SYSTEM."

0: Differential input, command pulse/direction
1: Differential input, forward/reverse pulse
2: Differential input, A/B phase pulse

11: Open collector input, forward/reverse pulse
12: Open collector input, A/B phase pulse
1 Power
This parameter is enabled only under position control.
You can select the signal format of the command pulse input terminal.
The pulse format of the command pulse input terminals [CA], [*CA], [CB] and [*CB] of the servo
amplifier can be specified.
The maximum input frequency is 1.0 MHz at differential input or 200 kHz at open collector input.
However, enter each signal so that the following conditions are satisfied (the same signal conditions
apply to CA, *CA, CB and *CB).
In case of A/B phase pulse, the rising or falling edge of the A-phase signal or B-phase signal is counted
as a single pulse, so that a single-pulse input is equivalent to four pulse counts.
