TQCPG
Factory Setting: 0.0
Settings -100.0 to 100.0%
(Pr. 07-22 setting=100%)
 This parameter is torque command. When Pr.07-22 is 250% and Pr.07-20 is 100%, the
actual torque command = 250%X100% X motor rated torque.
 The drive will record the setting before power off.

Factory Setting: 0
Settings 0 Digital keypad
1 RS485 serial communication (RJ-11)
2 Analog signal (Pr.03-00)
 When Pr.07-21 is set to 0, the torque command can be set in Pr.07-20.
 When Pr.07-21 is set to 1 or 2, Pr.07-20 is used to display torque command.

Factory Setting: 100
Settings 0 to 500%
 This parameter is for the max. torque command (motor rated torque is 100%).
 According to the formula of motor rated torque:

Factory Setting: 0.000
Settings 0.000 to 1.000 sec
 When the setting is too long, the control will be stable but the control response will be
delay. When the setting is too short, the response will be quickly but the control maybe
unstable. User can adjust the setting by the control and response situation.
