Torque Detection (Pr. 864); Low Speed Detection (Pr. 865) - Mitsubishi Electric FR-V560 Instruction Manual

Additional functions (Pr. 851 to Pr. 865)
4.34.5 Torque detection (Pr. 864
This function outputs a signal if the motor torque rises to or above the Pr. 864 setting.
The signal is used as operation and open signal for an electromagnetic brake.
Parameter Name
864 Torque detection
The signal turns on when the output torque rises
to or above the detection torque value set in Pr.
864.
It turns off when the torque falls below the
detection torque value.
Related parameters
TU signal terminal assignment ⇒ Set "35" in any of Pr. 190 to Pr. 192 and Pr. 195 (output terminal function selection).
4.34.6 Low speed detection (Pr. 865
This function outputs a signal if the speed falls to or below the Pr. 865 setting.
Parameter Name
865 Low speed detection
<Operation>
The signal is output during inverter operation under the
following conditions.
(1) Vector control with encoder
Motor speed ≤ Pr. 865 ... ON
Motor speed > Pr. 865 ... OFF
(2) Vector control without encoder
Speed estimated value ≤ Pr. 865 ... ON
Speed estimated value > Pr. 865 ... OFF
(3) V/F control
Output speed ≤ Pr. 865 speed equivalent ... ON
Output speed > Pr. 865 speed equivalent ... OFF
REMARKS
When "0" is set, low speed detection (LS signal) is output under position control only.
Related parameters
LS signal terminal assignment ⇒ Set "34" in any of Pr. 190 to Pr. 192 and Pr. 195 (output terminal function selection).
