NOTE
• P103 cannot be set below Minimum Frequency (P102)
• To set P103 above 120 Hz:
- Scroll up to 120 Hz; display shows
(flashing).
- Release s button and wait one second.
- Press s button again to continue increasing P103.
WARNING!
Consult motor/machine manufacturer before operating above rated frequency. Overspeeding the motor/machine may
cause damage to equipment and injury to personnel!

• P104 = time of frequency change from 0 Hz
to P167 (base frequency)
• P105 = time of frequency change from

EXAMPLE: IF P103 = 120 Hz, P104 = 20.0 s and P167 (base frequency) = 60 Hz; then the rate of frequency change from

0 Low (120, 200, 400, 480VAC)
* The default setting is 1 for all drives except
when using “reset 50” (Parameter P199,
selection 4) with 480V models. In this case,
the default setting is 0.

P108 = motor current rating x 100
SMV output rating
Example: if motor = 3amps and SMV = 4amps,
then P108 = 75%
NOTE
Do not set above rated motor current as listed on the motor dataplate. The motor thermal
overload function of the SMV is UL approved as a motor protection device. If the line
power is cycled, the motor thermal state is reset to cold state. Cycling power after an
overload fault could result in significantly reducing the motor life.
