Name
Value Range, Description and Preset Value
Range: 0=Disabled
Preset: 0
When enabled, automatically reduces applied motor voltage on light load.
Minimum value is 50% of nominal.
Range: Last four trips stored
Preset: N/A (Read Only)
Displays the last four trips as a coded fault. The codes are displayed most recent
first to oldest. Use the up or down arrow keys to scroll the fault list.
Range: 4-32kHz
Preset: 16
Sets the effective switching frequency of the drive. If "rED" is displayed, the
switching frequency has been reduced to the level in P00-14 due to excessive
drive heatsink temperature.
Range: 0 to 7
Preset: 1
Defines the function of the user relay (when operating conditions are met).
0: Drive enabled
1: Drive healthy
2: Motor at target speed
3: Drive tripped
Disabled: Contacts open
Options 4 to 7: the Relay output is enabled using the level set in P-25.
Custom scaling factor
Preset: 0.000
P-04 = 0, speed in Hz are scaled by this value.
P-04 > 0 RPM units are scaled by this value.
Scaled display values are preceded with "" for custom units.
