Gear Ratio For Simple Index Function; Index Angle For Simple Index Function; Deceleration Time For Simple Index Function - Delta VFD-B User Manual

Chapter 5 Parameters|VFD-B Series
This parameter is to delay the signals on digital input terminals. 1 unit is 2 msec, 2 units are 4
msec, etc. The delay time is used to debounce noisy signals that could cause the digital
terminals to malfunction.

Deceleration Time for Simple Index Function

Settings
The simple index function is used to position the machine/motor at the same position when it
stops. The function should be used with setting 34 for Multi-Function Input Terminals (04-04 to
04-09).
The function diagram is shown below. The machine is driven by a gear motor or other
reduction gearbox. The trigger position of the proximity sensor is used as the starting point of
the index angle. When the stop command is initiated, the AC motor drive will not decelerate
until the proximity sensor is triggered. After that the AC motor drive begins to decelerate and
stop according to the Pr.04-24 and Pr.04-25.
