Chapter 4 Explanation of Functions

When "00" (quadrant-specific setting mode) is specified for the torque limit selection (b040), the torque limits 1 to 4 apply as shown below.

Torque
Regeneration	Powering (b041)
(b042)
Reverse rotation	Forward rotation
(RV)	(FW)
Powering	Regeneration
(b043)	(b044)

When "01" (terminal-switching mode) is specified for the torque limit selection (b040), the torque limits 1 to 4 are set as shown in the example below. The torque limits 1 to 4 are switched by the torque limit switches 1 and 2 assigned to intelligent input terminals.

(Example) When torque limit switch 1 (41) and torque limit switch 2 (42) are assigned to intelligent input terminals [7] and [8], respectively:

When applying the torque limitation function to the motor operation at low speeds, also use the overload restriction function.

4.2.101 Reverse Run protection function

The reverse Run protection function is effective when "03" (sensorless vector control), "04" (0Hz-range sensorless vector control), or "05" (vector control with sensor) is specified for the V/F characteristic curve selection (A044/A244).

For control reasons, especially during motor operation at low speed, the inverter may output a frequency that instructs the motor to rotate in the direction opposite to that specified by the operation command. If the counterrotation of the motor may damage the machine driven by the motor, enable the counterrotation prevention function.
