Installing and Operating the SP200 AC Drive
Carrier Frequency Derating Curves
When using a carrier frequency greater than 2 kHz, the ambient temperature and/ or output current must be
limited to values less than the standard ratings for 1.5 HP and 2 HP drives. Units 1 HP and smaller do not
require derating. Use the graphs above to determine the maximum operating conditions when using a carrier
frequency greater than 2 kHz. For example, consider a 1.5 HP drive rated at 230 V and 6 A output. When set to
8 kHz carrier frequency and used in a 45
°
C ambient, the maximum output current is limited to 95% (5.7A).
P-63 Analog Input Display Units Model
A B C
Use this parameter to scale the units
for d-08 (Analog Input 1 Units) and
d-09 (Analog Input 2 Units) display
parameters. Enter the number to be
displayed at the maximum analog
input level.
Parameter Range: 0 to 9999 X X
Default Setting: 0 X X
Running Access: RW
P-64 Carrier Frequency Model
A B C
Use this parameter to set the carrier
frequency for the PWM output
waveform. Note that derating may be
required above 2 kHz (see below).
Parameter Range: 2 to 8 (kHz) X X X
Default Setting: 2 X X X
