This parameter changes the source for frequency command by using any Multifunction Input

(Pr.39-Pr.42, setting= 28).

Pr. 143

Software Braking Level

Unit: 0.1V

Settings 115V/230V series

370 to 450 Vdc

Factory setting: 380.0

460V series

740 to 900 Vdc

Factory setting: 760.0

575V series

925 to 1075 Vdc

Factory setting: 950.0

This parameter sets the level for the dynamic braking to operate. The setting value must be

higher than the steady-state DC BUS Voltage to prevent the braking transistor from having a

100%-duty. At 100% duty the transistor and resistor will most likely fail.

Pr. 144

Accumulative Motor Operation Day

Settings 00-65535 Days

Read Only

Pr. 145

Accumulative Motor Operation Time (Min.)

Settings 00-1440 Minutes

Read Only

These parameters display accumulative time of motor operation. They will not reset to zero

due to parameter reset to factory and will not re-calculate if the 65535 days limit is exceeded.
