Delta Electronics VFD-S manual Over-Torque Detection Mode OL2, 6-04, 6-05, 6-07

Chapter 5 ParametersVFD-S Series

6-03Over-Torque Detection Mode (OL2)

				Factory Setting: d0
	Settings	d0	Over-Torque detection disabled.
		d1	Enabled during constant speed operation. After the over-torque is
			detected, keep running until OL1 or OL occurs.
		d2	Enabled during constant speed operation. After the over-torque is
			detected, stop running.
		d3	Over-Torque detection enabled during running, and continues to run
			till OL1 or OL.
		d4	Enabled during running. After the over-torque is detected, stop
			running.
6-04	Over-Torque Detection Level			Unit: 1
	Settings	d30 to d200%		Factory Setting: d150
This setting is proportional to the Rated Output Current of the drive.
6-05	Over-Torque Detection Time			Unit: 0.1
	Settings	d0.1 to d10.0 sec		Factory Setting: d0.1

If a Multi-Function Output Terminal is set as Over-Torque Detection Indication and the output current exceeds the Over-Torque Detection Level (Pr.6-04, Factory Setting: 150%), the Over- Torque Detection Time (Pr.6-05, Factory setting: 0.1) and the setting of multi-function terminal is Over-Torque Detection Indication, the contact will be “close”.

6-06Electronic Thermal Overload Relay Selection

		Factory Setting: d2
Settings	0	Operate with a Standard Motor (self-cooled by fan)
	1	Operate with a Special Motor (forced external cooling)
	2	Operation disabled

This function is used to protect the motor from overloading or overheating.

6-07	Electronic Thermal Characteristic		Unit: 1
	Settings	d30 to d600Sec	Factory Setting: d60

The parameter determines the time required activating the I2t electronic thermal protection function. The graph below shows I2t curves for 150% output power for 1 minute.
