(6) PG pulse dividing ratio (20-29).
When the pulse output signal is connected to a pulse input device. Use 20-29 to set
the pulse divider ratio.
.Set 20-29 to present the first place n(0 or 1)as well as the second and the third place
k (001 to 320).
The following formula uses n, k to calculate the output proportion of cycle.
─ 20-29= □
□□ , Setting range n : 0 to 1
n k k :01 to 32
─ Output proportion = (1+n)/k
e.g. 20-29=001 → n=0, k=1, proportion = (1+0)/1=1
①
. 20-29=032 → n=0, k=32, proportion = (1+0)/32=1/32
②
. 20-29=132 → n=1, k=32, proportion = (1+1)/32=1/16
(7) Set the gear ratio of PG and motor (20-30,20-31).
. In V / F + PG control mode, there is transmission device between PG and the
motor (the response speed of V / F + PG mode is less than that of SV mode).
. Set the gear ratio of the motor and PG as following:
─ Set the gear ratio of the load side of 20-31.
─Set the gear ratio of the motor side of 20-30
─Motor speed will be calculated in accordance with the following formula:

(1) Torque control selection (21-00)
. In SV control mode, switch the speed and torque controls based on the following:
. Set one of multi-function digital input terminals from 03-00 to 03-08 to 44, (speed /
torque control switching)
. When the input of this terminal is off, the speed control is enabled; when the input
of this terminal is on, the torque control is enabled.
. Set 21-00 to select speed control or torque control
21-00= 0: speed control ( 20-00, 20-09), ASR setting
= 1: torque control (21-01 to 4), torque control setting
Refer to figure 4.3.108 for the speed control architecture. Refer to the below figure
4.3.121 for torque control architecture.
