Learning Basic Features
• To prevent overheating or damaging the motor, do not apply power braking to the loads that
require frequent deceleration.
• Stall prevention and power braking only operate during deceleration, and power braking
takes priority over stall prevention. In other words, when both Pr.50 (stall prevention and flux
braking) and Ad.08 (power braking) are set, power braking will take precedence and operate.
• Note that if deceleration time is too short or inertia of the load is too great, an overvoltage
fault trip may occur.
• Note that if a free run stop is used, the actual deceleration time can be longer than the pre-
set deceleration time.

Description
dr.19 Start Freq
Set the lower limit value for speed unit parameters that are expressed in Hz
or rpm. If an input frequency is lower than the start frequency, the parameter
value will be 0.00.
dr.20 Max Freq
Set upper and lower frequency limits. All frequency selections are restricted
to frequencies from within the upper and lower limits.
This restriction also applies when you in input a frequency reference using
the keypad.
