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:
D5-05 Speed Limit Bias Speed Lmt Bias - - - A
D5-06 Reference Delay Timer Ref Hold Time - - - A
