4.4 Description of Parameters
P01 LINE VOLTAGE SELECTION
Parameter P01 calibrates the drive for the actual applied input voltage. Set this parameter to HIGH
(01) for 120, 220-240, and 460-480 Vac input, or LOW (02) for 200-208 and 380-415 Vac input.
NOTE
If this parameter is changed while the drive is running, the new value will not take effect
until the drive is stopped.
P02 CARRIER FREQUENCY
Parameter P02 sets the switching rate of the output IGBT’s. Increasing the carrier frequency will result
in less audible motor noise. Available settings are: 4 kHz, 6 kHz, 8 kHz, and 10 kHz.
Parameter

Frequency
Ambient
or Output Derate
01 4 kHz 40°C or 100%
02 6 kHz 40°C or 100%
03 8 kHz 40°C or 100%
04 10 kHz 35°C or 92%
NOTE
•
The SCL/SCM drive is fully rated up to 8 kHz carrier frequency. If the 10 kHz carrier
frequency is selected, the drive’s ambient temperature rating OR output current
rating must be de-rated to the value shown in the table above.
• If this parameter is changed while the drive is running, the change will not take
effect until the drive is stopped.
P03 START METHOD
WARNING!
Automatic starting of equipment may cause damage to equipment and/or injury to
personnel! Automatic start should only be used on equipment that is inaccessible to
personnel.
01 NORMAL: The drive will start when the appropriate contact is closed on the terminal strip.
Refer to Section 3.6 for possible control configurations.
02 START ON POWER UP: The drive will automatically start upon application of input power.
03 START WITH DC BRAKE: When a START command is given, the drive will apply DC BRAKE VOLTAGE
(Parameter 22) for the duration of DC BRAKE TIME (Parameter 21) prior to starting the motor
to ensure that the motor is not turning.
