Over-Voltage Stall
Program
Protection
Stall
This parameter
Enables/Disables
the
Over-Voltage Stall
function. When
enabled, this function causes the drive to extend the decel time when the DC
bus voltage increases due to transient voltage spikes, regeneration, supply
voltage out of specification, etc. in an attempt to reduce the bus voltage.
Settings:
0 — Enabled
1 — Disabled
2 — Enabled (Forced Shorted Deceleration)
Direct Access Number — F305
Parameter Type —
Selection List
Factory Default —
Enabled
Changeable During Run —
Yes
Motor #1 Max Output Voltage
Program
Motor Parameters
Motor Set #1
This parameter sets the maximum value of the output voltage of the drive. The
Motor #1 Maximum Output Voltage
is the
Motor
#1
output voltage at the
Base Frequency
). Regardless of the programmed value, the output
voltage cannot be higher than the input voltage.
The actual output voltage will be influenced by the input voltage of the ASD
and the
Supply Voltage Compensation
setting (
Direct Access Number — F306
Parameter Type —
Numerical
Factory Default — (ASD dependent)
Changeable During Run —
Yes
Minimum — 0.0
Maximum — 600.0
Units — Volts
Supply Voltage Compensation
Program
Protection
Base Frequency Voltage
This parameter
Enables/Disables
the
Voltage Compensation
function. This
function provides an output waveform adjustment that compensates for changes
in the input voltage.
Settings:
0 — Enabled (box checked)
1 — Disabled
Direct Access Number — F307
Parameter Type —
Check Box
Factory Default —
Enabled
Changeable During Run —
No
