EM303B General Purpose Inverter
120
F5-22=1
Negative torque prohibited.
F5-13 and F5-23 will be blocked.
F5-22=0
Negative torque permitted.
F5-13 defines the torque output direction.
F5-23
is for setting the transit time at zero
output torque for the inverter in the process
of switching positive and negative torque.
See Figure 7-19.
The torque direction refers to the setting
direction of torque current, but not the
rotational direction of motor.

Deadband of Positive/Negative Torque
1.
The default forward direction of motor is the positive torque direction.
2.
If positive/negative torque switching is applied in torque program operation
mode, it cannot be switched by terminals.

F5-24 and F5-25
are PID regulator parameters of torque current, and will affect system
performance and stability directly. User does not need to change the defaults on general

F5-27
is for the control mode of inverter output frequency near zero frequency.
F5-27=0
Brake current at zero frequency can be set by F7-31, and it will make motor not be
driven by the load when the output frequency of inverter is zero frequency.
F5-27=1
Normal output control.
F5-27=2
There is no output near zero frequency. Motor can rotate freely.
No.
