Load Pattern Selection (Pr. 14 ) - Mitsubishi Electric FR-S500E Instruction Manual

2.3.9 Load pattern selection (Pr. 14
You can select the optimum output characteristic (V/F characteristic) for the
application and load characteristics.
Pr.14=0
For constant-torque
loads
(e.g. conveyor, cart)

CAUTION
1. When automatic torque boost control is selected, this parameter setting is
ignored.
2. Pr. 46 "second torque boost" is made valid when the RT signal turns on.
The RT signal acts as the second function selection signal and makes the
other second functions valid.
