Mitsubishi Electric FR-A800 Series Instruction Manual page 389

NOTE
• The stall prevention operation level is automatically lowered according to the cumulative value of the electronic thermal O/L
relay so as to prevent an inverter overload trip (E.THT) and the motor overload trip (E.THM) from occurring.
 Lift operation adjustment (Pr.61, Pr.64)
• The application range can be expanded by setting the parameters for adjustment of Pr.61 and Pr.64.

*1 The setting range of the FR-A820-03160(55K) or lower and the FR-A840-01800(55K) or lower
*2 The setting range of the FR-A820-03800(75K) or higher and the FR-A840-02160(75K) or higher
NOTE
• Even if the lift operation has been selected, inputting the JOG signal (JOG operation), RT signal (Second function selection)
or X9 signal (Third function selection) during an inverter stop will disable the automatic acceleration/deceleration and give
priority to JOG operation, second function selection or third function selection. Note that during operation, an input of JOG and
RT signal does not have any influence even when the automatic acceleration/deceleration is enabled.
• Even if Pr.61 and Pr.64 are set, changing Pr.292 automatically resets to the initial setting (9999). Set Pr.61 and Pr.64 after
setting Pr.292.

Description
Set the rated motor current value such as when the motor capacity and
inverter capacity differ.
Set the reference current (A) of the stall prevention operation level.
The rated inverter output current value is the reference.
Set the starting frequency for the lift operation.
The starting frequency is 2 Hz.
