Over-Torque Detection Mode (Ol2); Over-Torque Detection Level (Ol2) - Delta VFD-M-D series User Manual

Output Frequency
Run/Stop
DC Braking during Start-up is used for loads that may move before the AC drive starts. Under
such circumstances, DC Braking can be used to hold the load in position before setting it in
motion.
DC Braking during stopping is used to shorten the stopping time and also to hold a stopped
load in position. For high inertia loads, a dynamic braking resistor may also be needed for fast
decelerations.

Over-Torque Detection Mode (oL2)

Settings
This parameter determines the operation mode of the drive after the over-torque (oL2) is
detected via the following method: if the output current exceeds the over-torque detection level
(Pr.7-06) longer than the setting of Pr.7-07 Over-Torque Detection Time, the warning message
"oL2" is displayed. If a Multi-Functional Output Terminal is to over-torque detection (Pr.6-00~6-
07=03), the output is on. Please refer to Pr.6-00~6-07 for details.

Over-Torque Detection Level (oL2)

Settings
This setting is proportional to the Rated Output Current of the drive.

00 Over-Torque detection disabled.
01 Over-Torque detection enabled during constant speed operation.
After over-torque is detected, keep running until oL2 occurs.
02 Over-Torque detection enabled during constant speed operation.
After over-torque is detected, stop running.
03 Over-Torque detection enabled during acceleration/constant speed
operation. After over-torque is detected, keep running until oL2
occurs.
04 Over-Torque detection enabled during acceleration/constant speed
operation. After over-torque is detected, stop running.
