Pa1_29 Speed Coincidence Range; Pa1_30 Zero Speed Range; Pa1_31 Deviation Unit Selection - Fuji Electric Alpha7 VV User Manual

CHAPTER 4 PARAMETER

PA1_29 Speed coincidence range

No.
29 Speed coincidence range
Enter the range in which the "speed coincidence" output signal is turned on.
The speed coincidence signal is turned on if the actual servomotor rotation speed is nearly the
command speed.
In case of a default value of 50 [r/min], the speed coincidence signal is turned on in the range of ±50
[r/min] to the command speed.
If the command speed is not reached due to PA1_25 (maximum rotation speed), override or similar, the
signal is turned off.
4
The speed coincidence signal does not turn on if the [FWD] or [REV] signal is turned off.

Descriptions.

PA1_30 Zero speed range

No.
30 Zero speed range
Enter the activation level of the "zero speed" output signal.
The signal is turned on at servomotor rotation speeds within the reference value.

PA1_31 Deviation unit selection

No.
31 Deviation unit selection
Enter the unit of position deviation.
Select 0 (unit amount) for the unit after multiplication by the electronic gear ratio. [Unit] is displayed.
Select 1 (pulse amount) for the unit before multiplication by the electronic gear ratio. (Unit of encoder
pulse amount)
This setting is related to the unit of all position deviation monitored with the keypad, PC Loader or
monitor 1/2 signal.
