150% for 1 minute duration (inverse time characteristic) 180% for 0.5 seconds
Power Supply
Rated Input AC Voltage – 200 to 230 VAC 50/60 Hz, 3 phase (1/2 to 30 Hp)
– 380 to 400 VAC 50 Hz, 3 phase (1 to 300 Hp) CT
– 380 to 480 VAC 60 Hz, 3 phase (1 to 300 Hp) CT
– 460-480 VAC, 60 Hz, 3 phase, 40 Hp and above, variable torque applications only
Voltage - +10%, -15%; Voltage Unbalance - Within 3%; Frequency - +/-5% Units are
dual rated Constant Torque/Variable Torque. Drive looks for a similar Volts/Hz ratio).
Control System Sinusoidal PWM Control (or with torque-vector control.)
Momentary Voltage Dip When the input voltage dips below 165 VAC (230V System), 310 VAC (460V system) or
400 VAC (575V System), the Drive can operate for 15 ms with 85% full load applied.
Starting Torque 150% (when torque vector control is active.)
Carrier Frequency – 2 to 15 KHz (1/2 to 30 Hp) 230 & 460 VAC
– 2 to 10 KHz (40 to 75 Hp) – 2 to 6 KHz (100 Hp and greater)
