Overvoltage Inhibit Function - YASKAWA Varispeed G7 Series Instruction Manual



Overvoltage Inhibit Function

Leave L3-11 (Overvoltage inhibit function selection) set to 0 (disabled). This function is used to prevent over-
voltage tripping when the braking resistor is not used with a regenerative load. When this function is enabled,
the torque reference on the regenerative side is automatically inhibited in the Inverter during regeneration.
Using this function in elevating machines is dangerous because the elevator may slip and fall.
Contact your Yaskawa representative for details on applications such as high-speed elevators (speed: 2 m/s or higher),
direct-drive elevators, or Inverters designed for cranes.
