4-82 Revision May 2008, ME14, SW V3.04
Pr. 141
Save Frequency Set Point
Factory Setting: 01
Settings 00 Not Save
01 Save
This parameter is used to save the frequency setting before powering off.
Pr. 142
Second Source of Frequency Command
Factory Setting: 00
Settings 00 Keypad Up/Down
01 AVI (0-10V)
02 ACI (4-20mA)
03 RS485
04 Keypad Potentiometer
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.
Pr. 146
Line Start Lockout
Factory Setting: 00
Settings 00 Disable
01 Enable
