50 VS-616G5 Programming Manual

Setting Range: 0 to 120%

Factory Default: 10%

Sets the speed limit bias value in the torque control mode as a percentage of the maximum output fre-

quency.

Setting Range: 0 to 1000ms

Factory Default: 0ms

Sets delay time from when the speed/torque control selection is made to when the control mode is

actually changed, in units of 1ms.

Torque Control Operation

To select torque control, set torque selection (D5-01) to “1”, or close the multi-function contact input

set to speed/torque control (H1-__ = “71”) and set terminal 16 function selection to torque reference

(H3-05 = “13”).

*1: When speed limit selection (D5-03) is set to “1”, the master frequency reference input from termi-

nal 13 or 14 becomes the speed limit; when speed limit selection (D5-03) is set to “2”, the set value

of D5-04 becomes the speed limit.

*2: When terminal 14 function selection is set to torque compensation (H3-09 = “14”), terminal l4 set

value can be used as the torque compensation value.

When torque reference > 0 and speed limit > 0 (winder application sequence), the following sequence

is activated:
