Parameter Acceleration and deceleration
FR-E700 SC EC/ENE 6 - 81
Adjustment of shortest acceleration/deceleration mode (Pr. 61 to Pr. 63)
By setting the adjustment parameters Pr. 61 to Pr. 63, the application range can be made wider.

Range
Description
61 Reference current
0–500 A
For example, when the motor and inverter are different in capacity, set
the rated motor current value.
Set reference current (A) of the stall prevention operation level during
acceleration/deceleration.
9999
(initial
value) The rated inverter current is defined as reference.
62
63
Reference value at
acceleration
Reference value at
deceleration
0–200%
Set when it is desired to change the reference level of acceleration and
deceleration.
Set the stall prevention operation level (ratio to the current value of
Pr. 61) during acceleration/deceleration.
9999
(initial
value)
The 150% value during shortest acceleration/deceleration is judged as
the stall prevention operation level.

NOTE
Since the Pr. 61 to Pr. 63 settings automatically return to the initial value (9999) if the Pr. 292 setting
is changed, set Pr. 292 first when you need to set Pr. 61 to Pr. 63.
