Zero deviation: Sequence output signal (Reference value 23)
The signal is turned on if the deviation (deviation amount) retained in the servo amplifier becomes
within the reference value under position control.
Whether the servomotor has reached close to the command position can be checked.
Function
The signal is turned on if the difference (deviation amount) between the command position and
feedback position is within the reference value of PA1_32 (zero deviation width/in-position range).
Position deviation will not be generated despite the reference value of PA1_32.
Parameter setting
To assign the zero deviation to IQ area (sequence output terminal), specify the corresponding
value ("23") to the output terminal function setting parameter.
Zero speed [NZERO]: Sequence output signal (Reference value 24)
The signal is turned on if the servomotor rotation speed is nearly zero.
Function
The signal is turned on if the servomotor rotation speed is within the reference value of PA1_30
(zero speed range).
The signal can be used as a motor stopping condition signal.
Parameter setting
To assign the zero speed [NZERO] to IQ area (sequence output terminal), specify the
corresponding value ("24") to the output terminal function setting parameter.
Speed coincidence [NARV]: Sequence output signal (Reference value 25)
The signal is turned on after the servomotor rotation speed has reached the command speed.
Function
The signal is turned on if the servomotor rotation speed is within the reference value of PA1_29
(speed coincidence range).
The command speed is the reference values of PA1_41 to 47 (manual feed speed 1 to 7) or
reference values in IQ area.
The signal is enabled under speed control and position control (interrupt positioning) and in the
homing cycle. It is turned off under torque control. (VS type)
During manual operation, the signal is not output under the following conditions.
•
If the [FWD] or [REV] signal is turned off
•
If the speed does not reach due to PA1_25 (max. rotation speed (for position and speed control))
•
If the deceleration time is too long to reach the command speed
