Detailed Function Description
58
P3.10 defines the number of pulse per cycle of PG or encoder.
Notice: When P0.00 is set to be 1, P3.10 must be set correctly according to the
encoder parameter, otherwise the motor will run abnormally. If the motor still run
abnormally when P3.10 has been set correctly, please change the PG direction
(P3.11).

0：Torque control is disabled. Inverter will run at speed control mode. Output torque of
inverter which should not greater than torque limit (P3.14) matches the torque of load
automatically. When the torque of load is greater than torque limit, output torque will
remain as torque limit and output frequency will decrease automatically.
1~8: Torque control is enabled.
z When torque control takes effect,
if T
set
> T
load
, output frequency will increase continuously until it reaches upper
frequency limit.
If T
set
< T
load,
output frequency will decrease continuously until it reaches lower
frequency limit.
Inverter can run at any frequency between upper and lower frequency limit only
when T
set
= T
load.
z Torque control can be switched to speed control, vice versa.
Switching by multifunctional terminal: For example, if torque setting source is
AI1 (P3.12=2), the value of multifunction terminal S5 is set to 31 (Disable
torque control). When S5 is valid, control mode will switch from torque
control to speed control, vice versa.
When running at torque control mode, press STOP/RST, it will switch to
speed control automatically.
z If torque setting is positive, inverter will run forward; otherwise it will run reverse.
