Starting torque
• 150% min. / Rated speed of 10%
V/f control (IM motor)
V/f control (slip compensation)
V/f control with speed sensor (IM motor)
• 200% min./0.5 Hz
Vector control without speed sensor (dynamic vector control) (IM motor)
V/f control with speed feedback (Automatic torque boost)
Sensorless vector control
• 200% min./0.0 Hz (0 Hz torque control)
V
ector control with speed sensor (IM motor)
Vector control with speed and pole position sensor (PM motor)
To obtain 200% starting torque at low speed, consider raising the capacity of the
inverter to the next higher capacity.
• 200% min. / Rated speed of 10%
Vector control without speed and pole position sensor (PM motor)
To obtain these starting torques at low speed, the capacity of the inverter and
motor must be taken into consideration.
The maximum torque that can be used is limited when the current capacity match-
ed to the mode is exceeded.
Current capacity of 200% in HHD mode, 150% in HD mode, and 120% in HND and
ND modes
Protection function Overcurrent, Overvoltage, Undervoltage, Electronic thermal, Temperature error,
Ground-fault current at power-on, Inrush current protection circuit, Overload limit,
Incoming overvoltage, External trip, Memory error, CPU error, USP error, Commu-
nication error, Overvoltage suppression during deceleration, Power interruption
protection, Forced Stop, etc.
