Firmware block:
VOLTAGE CTRL
(47)
This block
• enables/disables overvoltage and
undervoltage control
• enables/disables automatic
identification of supply voltage
• provides a parameter for manual
definition of supply voltage
• shows the supply voltage value
used by the control program.

47.01
OVERVOLTAGE CTRL
(see above)
Enables the overvoltage control of the intermediate DC link. Fast braking of a high inertia load causes
the voltage to rise to the overvoltage control limit. To prevent the DC voltage from exceeding the limit,
the overvoltage controller automatically decreases the braking torque.
Note:
If a braking chopper and resistor or a regenerative supply section are included in the drive, the
controller must be disabled.
(0)
Disable
Overvoltage control disabled.
(1)
Enable
Overvoltage control enabled.
47.02
UNDERVOLT CTRL
(see above)
Enables the undervoltage control of the intermediate DC link. If the DC voltage drops due to input
power cut off, the undervoltage controller will automatically decrease the motor torque in order to keep
the voltage above the lower limit. By decreasing the motor torque, the inertia of the load will cause
regeneration back to the drive, keeping the DC link charged and preventing an undervoltage trip until
the motor coasts to stop. This will act as a power-loss ride-through functionality in systems with high
inertia, such as a centrifuge or a fan.
(0)
Disable
Undervoltage control disabled.
(1)
Enable
Undervoltage control enabled.
