Checking Of Current Input On Analog Input Terminal - Mitsubishi Electric 800 Series Instruction Manual

(c) Adjust only torque without adjustment of gain voltage (current).
(When changing the gain torque from 150% to 130%.)
Parameter selection
Read Pr.920 for terminal 1.
1.
Read Pr.933 for terminal 4.
The present set value is displayed. (150.0%)
Torque setting change
2.
Turn to change the set value to "130.0%".
Press [SET] to enter the setting. "130%" is set in Pr.920 (Pr.933).
Checking the mode/monitor
3.
Change the status to the monitor mode.
Start
4.
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 torque setting are too close, an error (Er3) may displayed at setting.
• For operation outline of the parameter unit (FR-PU07), refer to the Instruction Manual of the FR-PU07.
• Set the bias torque setting using the Pr.919 or Pr.932. (Refer to
CAUTION
 Be cautious when setting any value other than "0" as the bias torque at 0 V (0 mA). Even if a torque
command is not given, simply turning ON the start signal will start the motor at the preset frequency.

Checking of current input on analog input
terminal
When current is input to the analog input terminal 2 and terminal 4, operation when the current input has gone below
the specified level (loss of analog current input) can be selected. It is possible to continue the operation even when the
analog current input is lost.

Setting range
Continues the operation with output frequency
1
before the current input loss.
4 mA input fault is activated when the current
2
input loss is detected.
Decelerates to stop when the current input loss
3 is detected. After it is stopped, 4 mA input fault
(E.LCI) is activated.
4 Continues operation with the Pr.777 setting.
9999 No current input check
Set the frequency to continue operation when
0 to 590 Hz the current input is lost.
(Valid when Pr.573 = "4")
9999 No current input check when Pr.573 = "4"
0 to 10 s Set the current input loss detection time.
