SGDH Amplifier Ratings and Specifications
*1 Supply voltage must not exceed 480V + 10% (528V). A stepdown transformer is required if the
voltage exceeds this limit.
*2 Use the servo amplifier within the ambient temperature range. When enclosed, the temperatures
inside the cabinet must not exceed the specified range.
*3 Speed regulation is defined as follows:

Note:
Power supply for DB contactor is made from DC24V
power supply. In case the DB operation is
necessary when power interruption occurs,
maintain the DC24V while the DB operates.
If 5 times inertia is attached and standard DB
resistor is used, DB operation time is about 2 to 5
seconds
40 Watt
Control Mode Three-phase, full-wave rectification IGBT PWM (sine-wave driven)
Feedback Incremental encoder, absolute encoder

Speed Selection
Forward/reverse rotation current control signals are used (1st to 3rd speed
selection). When both signals are OFF, the motor stops or enters another
control mode.
