Mitsubishi Electric FR-A820-00046 Instruction Manual page 382

(E) Environment setting parameters
Initial values differ depending on the rating as follows.
Pr.
0 [%]
7 [s]
8 [s]
12
[%]
Tab. 5-72:Initial values of Pr. 0, Pr. 7, Pr. 8 and Pr. 12 depending on Pr. 570 setting
The rated current and motor capacity differ depending on the inverter capacity. Refer to the
inverter rated specifications (page 8-1).
The initial value for FR-A820-00077(0.75K) or lower and FR-A840-00038(0.75K) or lower, is set to
85% of the rated inverter current.
● Setting Pr. 292 "Automatic acceleration/deceleration" = "5 or 6 (lift mode)" will change the stall
prevention operation level as shown below.
Pr.
292
Tab. 5-73:
NOTES When Pr. 570 = "0" (SLD rating), carrier frequency automatic reduction is enabled regardless of the
setting in Pr. 260 "PWM frequency automatic switchover".
To use the FR-A820-03160(55K) and FR-A840-01800(55K) in the LD and SLD ratings, a DC reactor,
which is available as an option, corresponding to the applied motor is required.
Setting the LD or SLD rating to the FR-A820-03160(55K) and FR-A840-01800(55K) changes their
parameter setting increments and setting ranges in the same way as for the FR-A820-03800(75K)
and FR-A840-02160(75K) or higher. For example, the setting increment and the setting range of
Pr. 9 will change from "0.01 A" to "0.1 A" and from "0 to 500 A" to "0 to 3600 A". For the setting of
each parameter, refer to the parameter list (on page 5-2).
