Additional Adjustment Parameters for Material Handling

Table 7 lists the additional parameters that are accessible when the

macro-configuration is set to Material Handling.

NOTE: UFr and

SLP are unitless

values. The

percent value is

only to provide a

range for

adjustment. For

example, 50 on a

0 to 150 scale is

one third of the

maximum.

IR Compens. - % UFr

IR compensation

0 to 150% or

0 to 800%

100%

Allows adjustment of the default value of IR Compensation

or the value measured during auto-tuning. The adjustment

range is extended to 800% if the SPC parameter (special

motor) is set to Yes in the 3—Drive menu (see page 50).

Special motors include synchronous permanent magnet

motors, synchronous wound field motors, and synchronous

reluctance motors.

This parameter is used to adjust low speed torque for

optimal performance. Adjust this parameter to compensate

for the resistive voltage drop of the motor stator windings

and the conductors connecting the motor and drive

controller. This parameter is typically used to boost torque

performance at low speed operation. If an autotune is

performed, adjustment of this parameter is usually not

required.

Slip Comp. - % SLP

Slip compensation 0 to 150% 100%

Allows adjustment of the slip compensation around a fixed

value set by the nSP parameter (motor nominal speed) in

the 3—Drive menu (see page 43).

This parameter is used to adjust the slip compensation to

improve speed regulation. Induction motors develop torque

based on the slip, which is the difference between the

speed of the rotating magnetic field in the stator and the

speed of the rotor. As the load increases, the slip increases

to produce the necessary torque.

In applications where the change in speed due to slip is

undesirable, the slip compensation should be increased.

When this parameter is increased, the drive controller will

automatically increase the output frequency. The amount

of increase is proportional to the increase of the load,

allowing one setting for the entire speed range.
