Operation Method Of Positioning Control; Parameters To Be Set Before Positioning Control - Toshiba TOSVERT VF-AS3 Manual

2. Operation method of positioning control

This chapter describes the parameter setting necessary for positioning control and the operation procedure of the inverter.

2.1 Parameters to be set before positioning control

Set necessary parameters for positioning control. For how to set, see the following table.
For the parameter settings to use
- PG feedback option (VEC008Z), refer to E6582148.
- resolver option (VEC010Z), refer to E6582171.
- input terminal S4, and S5, refer to E6582183.
After making these settings, check that operation is possible with speed control.

Setting
Set to 10 when the detection accuracy
of the speed is low with a small
number of PG pulses or the PG not
connected directly to the motor when
an induction machine is driven.
Set the PG pulse number when the
PG is connected to the motor and the
PG pulse number multiplied by the
reciprocal of the reduction gear ratio
when the PG is connected to the load
machine.
Select the PG and polarity to be used.
• Set 0 or 10 to input the speed
• Set 1 or 11 to use the PG feedback
• Set 3 or 13 to use the resolver
