Mitsubishi Electric 800 Series Instruction Manual page 338

 Method to adjust only stall prevention operation level without adjusting gain voltage (current).
(When changing the gain value from 150% to 130%.)
Operating procedure
1.
Parameter selection
Read Pr.920 for terminal 1.
Read Pr.933 for terminal 4.
The present set value is displayed. (150.0%)
2.
Torque setting change
Turn to change the set value to "130.0%".
Press [SET] to enter the setting. "130%" is set in Pr.920 (Pr.933).
3.
Checking the mode/monitor
Change the status to the monitor mode.
4.
Start
Turn ON the start switch (STF or STR) to apply a voltage across terminals 1 and 5 (4 and 5),
Operation is performed with 130% torque.
NOTE
• If the gain and bias of the stall prevention operation level are too close, an error (Er3) may be displayed at setting.
• For operation outline of the parameter unit (FR-PU07), refer to the Instruction Manual of the FR-PU07.
• Set the bias setting using the Pr.919 or Pr.932. (Refer to
