Revision Jan. 2009, 06EE, SW--PW V1.12/CTL V2.12 4-111
 Setting 1 or 2: it is used to detect with constant speed. For setting 2, it will free run to stop after
over-torque is detected.
 Setting 3 or 4: it is used to detect during acceleration. For setting 4, it will free run to stop after
over-torque is detected.
 Related parameters: Pr.03.00(Multi-function Output Relay (RA1, RB1, RC1)), Pr.03.01(Multi-
function Output Terminal MO1), Pr.06.01(Over-Current Stall Prevention during Accel),
Pr.06.02(Over-Current Stall Prevention during Operation) Pr.06.04(Over-Torque Detection
Level) and Pr.06.05(Over-Torque Detection Time)
06.04 Over-Torque Detection Level (OL2) Unit: 1
Settings 10 to 200% Factory Setting: 150
06.05 Over-Torque Detection Time (OL2) Unit: 0.1
Settings 0.1 to 60.0 sec Factory Setting: 0.1
 Pr.06.04 is proportional to the Rated Output Current of the drive.
 Pr.06.05 sets the time for how long over-torque must be detected before “OL2” is displayed.
 The method to detect over-torque is shown as follows:
1. when output current exceeds over-torque detection level (Pr.06.04)
2. when over-torque time exceeds over torque detection time (Pr.06.05)
If a Multi-function Output Terminal is set to over-torque detection (Pr.03.00~03.01=04), the
output is on. Please refer to Pr.03.00~03.01 for details.
 For general motor, the output torque and output current of the AC motor drive will in proportion
in V/f control. Thus, it can use the output current of the AC motor drive to limit the output
torque of motor.

Pr.03.01(Multi-function Output Terminal MO1)
06.06 Electronic Thermal Overload Relay Selection (OL1)
Factory Setting: 2
Settings 0 Operate with a Standard Motor (self-cooled by fan)
1 Operate with a Special Motor (forced external cooling)
2 Operation disabled
 This parameter is used to set the operation selection of the electronic thermal overload relay.
