Product Description:

R63GSSA-HS-SS-NV-03 is the product name of R series servo mechanical motor designed for the industrial automation purposes. It is a maintenance free digital AC control servo motor that does not need any repairing during the entire lifecycle. This synchronous motor is manufactured by Pacific Scientific, which has been now acquired by the Kollmorgen Inc. Kollmorgen is a headquartered in Baltimore in the State of Maryland, USA.

This motor is designed for the improved dynamic responses and faster acceleration and deceleration with demagnetization of the field owing to its feature of high torque to inertia. It operates at 240V AC. It is a brushless motor and uses electronic circuit for electric commutation purpose to shift the phases of the electric motors. It is a 4 pole pair servo motor that uses permanent magnet as the field exciter.

The frame size of this servo motor is 5.75 x 5.75 square inches height and lengths respectively. The weight of this motor is about 29 pounds and can produce the peak torque power of about 20.5 Nm. It is able to produce about 8.3 Nm continuous stall torque. It uses G category of winding, which is able to sustain as much as 33 amperes of maximum currents at peak torque. The rated speed of this servomotor is 3400 rpm. It is 3 magnet stack motor.

This motor is designed for special shaft mounting and modifications. It uses hall sensor for the feedback as mentioned with HS in the name code. The SS in the name code refers to the special feedback. The shaft of this servo digital AC control motor has no shaft seal option as indicated by NV in the name code of this motor. R63GSSA-HS-SS-NV-03 motor has 3 custom parts as indicated in the name code.

Drive LED blink-count	What it usually means	Corrective action you can try first
2 blinks – Motor Over-Temp	Winding PTC ≥ 155 °C: ambient > 40 °C, blocked airflow, or duty cycle > 8.3 Nm cont. rating	Stop axis, let motor cool, clear shroud/vents, verify fan flow; cut continuous torque or lengthen cycle time.
3 blinks – Drive Over/Under-Temp	S200 heatsink < 0 °C or > 100 °C	Keep cabinet 0-45 °C, clean/replace drive fan & filter, ensure 50 mm clearance round heatsink.
4 blinks – Drive I·t trip	Drive’s RMS-current/time product exceeded (long accel, stalled load)	Lengthen accel/decel ramps; check for mechanical jams; compare load inertia to motor (≈ 0.019 kg m²).
5 blinks – Motor I²t trip	Average shaft torque > 8.3 Nm for too long	Verify sizing; if cycle hasn’t changed, consider higher-torque H/C winding motor; clean fan path.
7 blinks – Bus Over-Voltage	DC-bus > 410 V during regen (fast stop, brake resistor open)	Ohm-check resistor, add larger (≥ 100 Ω / 100 W) bleeder, soften decel-time parameter.
8 blinks – Bus Under-Voltage	AC line sag or undersized transformer	Measure bus while accelerating; stiffen mains, add line reactor, check tap selection.
9 blinks – Motor phase short	l-l or l-g fault: oil in MS connector, crushed cable, winding short	Meg-ohm test motor & leads (> 500 MΩ @ 500 V), dry / replace components, reseat connector.
10 blinks – Peak over-current	Instantaneous current > 33 A (spec limit for “G” winding)	Remove mechanical crash, lower peak-torque limit in drive, add compliant stops.
11 blinks – Hall / resolver fault	Illegal Hall sequence (HS) or feedback noise	Reseat 10-pin feedback plug, verify 360° shield clamp, re-run resolver alignment if fitted.
19 blinks – Position error too large	Following error beyond window (loose coupling / gains too low)	Tighten shaft coupling, check belts, raise P-gain 10 %, auto-tune again; log following error.

Frequently Asked Questions about R63GSSA-HS-SS-NV-03:

Q: Can the R63GSSA-HS-SS-NV-03 industrial motor be installed outside the control cabinet?

A: The enclosure of the R63GSSA-HS-SS-NV-03 industrial motor provides it with protection against solid substances and water splashes. This high degree of protection makes it possible for the motor to operate efficiently without a control cabinet.

Q: How can operators detect operational error in the R63GSSA-HS-SS-NV-03 motor?

A: The R63GSSA-HS-SS-NV-03 motor features a resolver which communicates the operational status of the motor to the drive controller. Operators can detect errors through the display unit of the drive controller.

Q: What type of electrical cable should be used for the wiring of the R63GSSA-HS-SS-NV-03 motor?

A: Pacific Scientific produce standardized cables that are compatible with the R63GSSA-HS-SS-NV-03 motor. These cables should be ordered by operators as separate unit.

Q: Does the R63GSSA-HS-SS-NV-03 motor require an external air blower for operation?

A: The motor can operate very well without an external air blower. The use of the air blower will only be required when the motor is used in a very hot industrial environment, or when the motor is required to under go continuous start-stop operation at high frequency.

Q: What is the appropriate environmental condition for the operation of the R63GSSA-HS-SS-NV-03 motor?

A: The R63GSSA-HS-SS-NV-03 industrial motor should be used at an ambient temperature that falls between 0 to about 450C. The relative humidity around the motor should not exceed 95%, and the motor should not be used at an height that exceeds 1000 meters above sea level.

Internal Product Review

‘‘The R63GSSA-HS-SS-NV-03 manufactured by Pacific Scientific is an easy addition to production lines. Standardized cabling from Pacific Scientific removes the hassle from sizing, labeling, and installation.’’
