Rockwell Automation 1336E IMPACT Adjustable Frequency AC Drive User Manual V 1-4.XX - Manual (Page 209)

Parameters 11-11
7 Motor Poles
Motor Poles contains the number of motor poles. The drive
calculates this value during the Quick Motor Tune portion of the
start up routine.
Note: Encoder PPR

Factory default 4 poles
Minimum value 2 poles
Maximum value 40 poles
Conversion 1 = 1
8 Encoder PPR
Encoder PPR contains the pulse per revolution rating of the
feedback device when you use an encoder to determine motor
speed.

Factory default 1024 ppr
Minimum value calculated
Maximum value 20000 ppr
Conversion 1 = 1
9 Service Factor
Enter the minimum level of current that causes a motor overload
(I
2 T) trip under continuous operation. Current levels below this
value never result in an overload trip. For example, a service
factor of 1.15 implies continuous operation up to 115% of
nameplate motor current.

Factory default 1.15
Minimum value 1.00
Maximum value 2.00
Conversion 4096 = 1.00
10 PWM Frequency
Enter the drive carrier frequency in Hz. The drive carrier
frequency depends on your application and drive size. The drive
carrier frequency affects the audible noise level of your motor.
