MHT260a (Engl.)
This signal will not be turned on for the following conditions:
1) Forward command [FWD] signal or reverse command [REV] signal is off.
2) When the motor speed does not reach the command speed due to the max. speed setting (basic para. 16).
3) Accel./decel. time is long and the speed does not reach the command speed.
■
Parameter setting
To allocate the speed arrive [NARV] signal to the control input terminal, set (25) to the system para.. If this signal is not allocated to the
control input terminal, this signal is deemed "always off”.

(1) Speed matching zone (width) (basic para. 51)
The [NARV] signal is turned on, when the motor speed is near the command speed (set by para.). As the initial value is 50 [r/min], the
[NARV] signal is on when the motor speed reaches the command speed
±
50 [r/min].
When the motor speed does not reach the command speed due to the max. speed setting (basic. para. 16) or override setting, this signal
turns off. When [FWD] or [REV] signal is off, the [NARV] signal does not turn on.
(2) Max. speed (basic para. 16)
This parameter specifies the max. value of motor speed.
If motor speed exceeds the max. speed by the override, the motor rotates at the setting value.
The setting of max. speed is not valid, during position control using pulse train input.
5.4 Origin return
The section explains origin return for determining a coordinate system and position preset.
Control input signal :
・
Origin return [ORG] (5) Control output signal :
・
Origin return end (22)
・
Origin LS [LS] (6)
・
Origin LS detection (40)
・
Position preset (16)

5.4.1 Origin return [ORG]
This function executes the origin return action and determines the origin.
Origin return [ORG] (Control input signal)
■
Function
This function executes the origin return action at the ON edge of [ORG] (5).
Origin return action depends on basic para. setting 72 to 77.
■
Parameter setting
To allocate the [ORG] signal to the control input terminal, set (5) to the system para..
