*1 80% output in the high-speed range. (The output is reduced when the speed is 2400 r/min or more. Contact us separately for details.)
*2 A dedicated motor of 3.7 kW or less can be run at the maximum speed of 3600 r/min. Consult our sales office when using the motor at the maximum speed.
*3 Power (current) at 50 Hz/60 Hz.
*4 Since a motor with brake has a window for gap check, the protective structure of both the cooling fan section and brake section is IP20. S of IP23S is an
additional code indicating the condition that protection from water intrusion is established only when a cooling fan is not operating.
*5 The value when high carrier frequency is set (Pr.72 = 6, Pr.240 = 0).
*6 The 12 V power supply is required as the power supply for the encoder.
*7 The cooling fan is equipped with a thermal protector. The cooling fan stops when the coil temperature exceeds the specified value in order to protect the fan
motor. A restrained cooling fan or degraded fan motor insulation could be causes for the rise in coil temperature.The cooling fan re-starts when the coil
temperature drops to normal.
*8 The cooling fan voltage and input values are the basic specifications of the cooling fan alone and free air values. The input value becomes slightly larger
when it is rotated by this motor due to an increased workload, but the cooling fan can be used as it is.When preparing a thermal relay at the user side, use
the recommended thermal setting.
Vector control dedicated motor SF-THY
*1 The 12 V power supply or the control terminal option (FR-A7PS) is required as the power supply for the encoder.
*2 A motor with a thermal protector is also available. Contact your sales representative.
