・Interrupt positioning accuracy
Interrupt input signal is affected by “hardware filter time 0.1ms and “software sampling time interval 0.2ms.
Interrupt input signal is on at the same time of sampling, or approximately 0.2ms later. Therefore, the signal input timing varies within
±0.1ms.
When mechanical equipment system moving speed N=1,000mm/s (60m/min),
1000 x 0.0001 = 0.1mm
The response rate of the sensor which will be used for interrupt input should be considered.
5.7.5 Fixed/passing point
Current position of motor can be checked.
Three types of output forms can be selected by the basic para. 62 setting.
1) Fixed point (basic para. 62 : 0)
This output signal is on when current position is near the basic para. setting point.
2) Passing point from off to on (basic para. 62 : 1)
This signal is on when current position is beyond the basic para. setting point. The signal is off when it is less than the setting point.
3) Passing point from on to off (basic para. 62 : 2)
This signal is on when current position is less than the basic para. setting point. The signal is off when it is beyond the setting point.
