VS-616G5 Programming Manual
Speed/Torque Control Switching
When the VS-616G5 is set up for flux vector control (A1-03 = “3”), speed control or torque control can
be selected “on the fly” by using the multi-function input speed/torque control selection command
(H1-__ = “71”).
Sequence Description
• When the speed/torque control selection contact is OFF, speed control is activated.
· Speed reference during speed control depends on the frequency reference selection (B1-01) set-
ting. To use terminal 13 or 14 as the master frequency reference, set Bl-0l to “l”.
· Torque limit during speed control is the smaller of the absolute value of terminal 16 torque limit,
or the values set in the torque limit parameters (L7-01 to L7-04).
· When a stop command is given during speed control, speed control is maintained and the
smaller of the absolute value of terminal l6 torque limit, or the values set in the torque limit
parameters (L7-01 to L7-04), is used as the torque limit. Then the motor decelerates to stop.
‚ When the speed/torque control selection contact is ON, torque control is activated.
· Speed limit during torque control is the master frequency reference at terminal 13 or 14 when
speed limit selection (D5-03) is set to “1”, and is the speed limit value (D5-04) when D5-03 =
“2”, regardless of the frequency reference selection (B1-01) setting.
· During torque control, the terminal 16 analog input value becomes the torque reference.
