P0151 – Actuation Level of the DC Link Voltage Regulation
Adjustable 339 to 1200 V
Range:
Properties: V/f, V V W
Access groups MOTOR
via HMI:
Description:
Voltage level to activate the DC Link Voltage regulation.
P0152 – Gain Proportional to the DC Link Voltage Controller
Adjustable 0.00 to 9.99
Range:
Properties:
V/f, VVW
Access groups MOTOR
via HMI:
Description:
Gain proportional to the DC link voltage controller.
When the option of P0150 is 1 or 3, the value of P0152 is multiplied by the "error" of the DC link voltage, seeing
that the error results from the difference between the actual DC link voltage (P0004) and the actuation level
of the DC link voltage regulation (P0151). The result is added directly to the inverter output speed in rpm. This
resource is normally used to prevent overvoltage in applications with eccentric loads.
