„ Setting the Control Method
Any of the following three control methods can be set.
Note: The motor and MxC must be connected 1:1. The MxC is capable of stably operating motors capacities rated at 75% to 100% of the capacity of the
MxC.
V/f Control Method (A1-02 = 0)
• Set either one of the fixed patterns (0 to E) to parameter E1-03 (V/f Pattern Selection), or enter “F” to spec-
ify a user-set pattern as required for the motor and load characteristics in E1-04 to E1-13 in Advanced Pro-
gramming Mode.
Simple operation of a general-purpose motor at 50 Hz: E1-03 = 0
Simple operation of a general-purpose motor at 60 Hz: E1-03 = F (default) or 1
If E1-03 = F, the default setting in the user setting
from E1-04 to E1-13 are for 60 Hz
• Perform Stationary Auto-Tuning for the line-to-line resistance only if the motor cable is 50 m or longer for
the actual installation or the load is heavy enough to produce stalling. Refer to the following section on
Auto-Tuning for details on Stationary Auto-Tuning for the line-to-line resistance only.
Open Loop Vector Control (A1-02 = 2)
Perform Rotational Auto-Tuning. Refer to the following section on Auto-Tuning for details on Rotational
Auto-Tuning.
Flux Vector Control (A1-02 = 3)
Perform Rotational Auto-Tuning. Refer to the following section on Auto-Tuning for details on Rotational
Auto-Tuning.
