Documented Legacy Drive Compatibility
Yaskawa documented the following period controller components for the optical-encoder configuration. Verify machine voltage, wiring, feedback configuration, and component revision before replacement or substitution.
| Component | Documented designation |
|---|---|
| Servopack | CPCR-FR01B97-R1S |
| DC reactor | X-5019 (3 mH, 2 A) |
| Power transformer | CPT-10042 (150 VA) |
| Frequency-to-voltage converter | JASP-FV00 series; complete suffix is system dependent |
Operating and Service Notes
- Rated torque requires the specified heat-dissipating aluminum plate at 25 °C.
- Viewed from the drive end, rotation is counterclockwise when the red motor lead is positive and the black lead is negative.
- Yaskawa recommends thermal-overload protection for the motor.
- With the optical encoder installed and the motor mounted horizontally, the documented shock limit is two vertical impacts at 10 G.
- The standard totally enclosed construction is not equivalent to the separately ordered dripproof enclosure.
