Yaskawa: Servopack SGDL-02AS
Two types of supply voltages are available, 100V and 200V.
Always use the SGML Servomotor and SGDL Servopack in pairs.
The SGML Servomotor cannot run without the SGDL Servopack. Do not plug the SGML Servomotor directly into the commercial power supply (Direct connection to the commercial power supply will damage the Servomotor.)
Always follow the specified installation method.
The Servopack generates heat. Install the Servopack so that it can radiate heat freely. Note also that the Servopack must be in an environment free from condensation, vibration and shock.
Perform noise reduction and grounding properly.
If the signal line is noisy, vibration or malfunction will result.
Separate high-voltage cables from low-voltage cables.
Use cables as short as possible.
Use at least class 3 grounding (ground resistance 100Ω or below) for the Servomotor and Servopack.
Never use a line filter for the power supply in the motor circuit.
Conduct a voltage resistance test under the following conditions.
Voltage: 1,500 Vrms AC, one minute
Braking Current: 18 mA
Frequency: 50/60 Hz
Voltage applied point: Between R, T terminals and frame ground (connect terminals R and T securely.)
Use a fast-response type ground-fault interrupter.
For a ground-fault interrupter, always use a fast response type or one designed for PWM inverters. Do not use a time-delay type.
Do not perform continuous operation under overhanging load.
Continuous operation cannot be performed by rotating the motor from the load and applying regenerative braking. Regenerative braking by the Servopack can be applied only for a short period, such as the motor declaration time.
The Servomotor cannot be operated by turning the power ON and OFF.
Frequently turning the power ON and OFF causes the internal circuit elements to deteriorate. Always start or stop the servomotor by using reference pulses.
SGDL Servopack is a book-shaped compact servo controller. Incorrect installation will cause problems. Always observe the installation described in manual. When the servopack is to be stored with the power cable disconnected, store it in the following temperature range: Between –20°C and 85°C.
