
C5-32: Integral Operation during Accel/Decel for Motor 2
Functions for motor 2 in the same way that C5-12 functions for motor 1.
Enables integral operation during acceleration and deceleration. Refer to
(V/f w/PG) on page 193 for more details.
No.
C5-32
Setting 0: Disabled
Integral operation occurs only during constant speed and not during acceleration or deceleration.
Setting 1: Enabled
Integral operation is always enabled.

C5-37, C5-38: Motor 2 Inertia, Motor 2 Load Inertia Ratio
These parameters function for motor 2 in the same way that C5-17 and C5-18 function for motor 1.
These parameters are set automatically when Inertia Tuning and ASR Tuning are performed for motor 2 in CLV and
CLV/PM control modes. Refer to Auto-Tuning on page 120
No.

C5-38

C5-39: ASR Primary Delay Time Constant 2
Sets the filter time constant in seconds for the time from the speed loop to the torque reference output when the Single
Drive KEB Ride-Thru 2 is enabled (L2-29 = 1). If oscillation occurs during Single Drive KEB Ride-Thru 2, then
gradually increase this setting in increments of 0.01 s.
Note: This parameter is not available in models CIMR-A4A0930 and 4A1200.


C6-01: Drive Duty Mode Selection
The drive has two different "duty modes" to select from based on the load characteristics. The drive rated current,
overload capacity, and maximum output frequency will change depending upon the duty mode selection. Use parameter
C6-01 to select Heavy Duty (HD) or Normal Duty (ND) for the application. The default setting is ND. Refer to
Duty and Normal Duty Ratings on page 438
No.

Characteristics
C6-01
Performance
Use Heavy Duty Rating for applications requiring a high overload
Application tolerance with constant load torque. Such applications include extruders
and conveyors.

Use Normal Duty Rating for applications in which the torque requirements
drop along with the speed. Examples include fans and pumps where a high
overload tolerance is not required.
