16: Frequency Detection 4
Setting Value Function
16 Frequency Detection 4
Note:
The detection level set with L4-03 is a signed value. The drive will only detect in one direction.
ON : The output frequency is higher than the value of L4-03.
OFF : The output frequency is less than the value of "L4-03 - L4-04," or it is not more than the
value of L4-03.

18: Torque Detection 2 (N.O.)
Setting Value Function
18 Torque Detection 2 (N.O.)
Use the L6 [Torque Detection] parameters to set torque detection.
ON : The output current/torque > L6-05 [Torque Detection Level 2], or the output current/torque <
L6-05 for longer than the time set in L6-06 [Torque Detection Time 2].
Note:
• When L6-04 ≥ 5, the drive will detect when the output current/torque is less than L6-05 for longer than L6-06.
• Refer to L6: Torque Detection on page 334

1A: During Reverse
Setting Value Function
1A During Reverse
ON : The motor is operating in the reverse direction.
OFF : The motor is operating in the forward direction or the motor stopped.

V/f OLV
The terminal activates when the output frequency is higher than the value of L4-03 [Speed Agree Detection Level(+/-)]. After
the terminal activates, the terminal stays activated until the output frequency = L4-03 - L4-04.
V/f OLV
The terminal activates when the drive detects overtorque or undertorque.
for more information.
V/f OLV
The terminal activates when the motor operates in the reverse direction.
