Moeller DV6-340 Series - Torque limitation (TRQ)

Programmable digital outputs

Torque limitation (TRQ)
When the set torque limits are reached or exceeded, the DV6
frequency inverter activates the digital output configured as TRQ.
This function is available only in vector mode (a Section
“Voltage/frequency characteristic and voltage boost“, Page 126):
• SLV (sensorless vector) control
• 0 Hz SLV control
• Vector control with optional DE6-IOM-ENC module
To use a TRQ output, you must first configure one of the digital
inputs 1 to 8 as TL (activate torque limitation) (a Section
“Torque limitation (TL), torque selection (TRQ1 and TRQ2)“,
Page 94).
Under PNU b040, specify how the torque limits are defined.
Under PNU b041 to b044, set the torque limits for the motor’s four
quadrants.
X To activate vector control, enter one of the following values
under PNU A044 (a Section “Voltage/frequency charac-
teristic and voltage boost“, Page 126).
– 03: SLV control
– 04: 0 Hz SLV control
– 05: Vector control with optional DE6-IOM-ENC module
X Under PNU b040, specify how the torque limits are defined.
X If you have entered the value 00 under PNU b040, enter the
torque limits for each of the motor’s four quadrants under
PNU b041 to b044.
X Program one of the digital inputs 1 to 8 as TL by setting the
corresponding PNU (C001 to C008) to 40.
X Program one of the digital outputs 11 to 15 as TRQ by entering
the value 10 in the corresponding PNU (C021 to C025) or under
PNU C026 for the signalling relay contacts K11-K12.
