Chapter 12 Description of Parameter SettingsC2000

Capacitor oH Warning Level
Default: Depending
on the model power
Settings 0.0–110.0 degree
Sets the over-heat warning level of the drive’s internal DCBUS capacitor.
When the setting is less than 10.0 degree, the drive uses its internal capacitor oH warning level.
Ripple of Input Phase Loss
Default:
30.0/60.0/75.0/90.0
Settings 230V series: 0.0–160.0 V
DC
460V series: 0.0–320.0 V
DC
575V series: 0.0–400.0 V
DC
690V series: 0.0–480.0 V
DC
Detected Input Phase Loss (OrP) Action
Default: 0
Settings 0: Warn and ramp to stop
1: Warn and coast to stop
When the drive detects the DC BUS ripple exceeds the setting for Pr. 06-52, and lasts for the time
of Pr. 06-50 plus 30 seconds, the drive executes the input phase loss protection according to Pr.
06-53.
During the time of Pr. 06-50 plus 30 seconds, if the DCBUS ripple drops lower than the setting for
Pr. 06-52, the Orp protection recalculates.
Derating Protection
Default: 0
Settings 0: Constant rated current and limit carrier wave by load current and
temperature
1: Constant carrier frequency and limit load current by setting carrier wave
2: Constant rated current (same as setting 0), but close current limit
The maximum output frequency and its corresponded carrier frequency lower limit under each
control mode:
VF, SVC and VFPG: 600Hz, 6K
FOCPG: 600Hz, 12K
FOC sensorless (IM): 300Hz, 6K
FOC sensorless (PM): 500Hz, 10K
Setting 0:
When the operating point is greater than the derating curve, the rated current is constant,
and carrier frequency (Fc) output by the drive decreases automatically according to the ambient
temperature, overload output current and overload time. If overloads are not frequent, and the
concern is only about the carrier frequency operating with the rated current for a long time, and
changes to the carrier wave due to short overload are acceptable, set to 0.
