NOTE
*1 The α40 differs from the conventional 40S in its outside dimensions and output characteristics.
*2 The rated output is guaranteed at the rated voltage.
(Amplifier input: 200/220/230V AC +10% –15%, 50/60 Hz "1Hz)
If the input voltage fluctuates, it is possible that the rated output cannot be obtained even when
such fluctuations are within the allowable fluctuation range.
*3 The output for a 0.5, a1 and a 2 is 15 min rated. That for a1.5 is 10 min rated.
*4 S3 40% for a 0.5 and a 30, S3 25% for a 1.5.
*5 The cycle time is 10 minutes, S3 60%: ON 6 minutes, OFF 4 minutes, S3 40%: ON 4 minutes,
OFF 6 minutes and S3 25%: ON 2.5 minutes, OFF 7.5 minutes.
*6 The rated current is the maximum current for each rated output.
*7 IC code conforms to IEC 34–6. TENV means totally enclosed and non–ventilated.
*8 IM code conforms to IEC 34–7.
*9 This is not a guaranteed value but a guideline for the maximum motor output at a rated supply
voltage. 120 % of 15 min rated for a 0.5, a 1 and a 2, and 120% of 10 min rated for a 1.5.
*10 Type conforms to IEC 34–11.
*11 128 teeth for motors with a high resolution magnetic pulse coder.
*12 These values are to be used only as guidance for selecting a power supply module and are
not guaranteed.
*13 Degree of protection: with oil seal: IP54, without oil seal: IP40.
