LSIS G100 User Manual

• 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 bit3 of 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.

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.
