n C5-32: Integral Operation during Accel/Decel for Motor 2
Functions for motor 2 the same way that C5-12 functions for motor 1. Enables integral operation during acceleration and
deceleration. Refer to C5-12: Integral Operation during Accel/Decel (V/f w/PG) on page 231 for details.
No. Parameter Name Setting Range Default
C5-32 Integral Operation during Accel/Decel for Motor 2 0, 1 0
Setting 0: Disabled
Integral operation occurs only during constant speed and not during acceleration or deceleration.
Setting 1: Enabled
Integral operation is always enabled.
n C5-37, C5-38: Motor 2 Inertia, Motor 2 Load Inertia Ratio
These parameters function for motor 2 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 157 for details on Auto-Tuning or enter the data manually.

n C6-01: Drive Duty Mode Selection
The drive has two different duty modes from which to select 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. Refer to Heavy Duty and Normal Duty Ratings on page 476
for details about the rated current.

Application
Use Heavy Duty Rating for applications requiring a high
overload tolerance with constant load torque, such as
extruders and conveyors.
Use Normal Duty Rating for applications in which the torque
requirements drop along with the speed, such as fans and
pumps where a high overload tolerance is not required.
