Note that these are 42-frame step motors which are not very common as they require high current stepper drives which are also not common. Many of these have been successfully upgraded to servo motors & drives. Servo motors are more accurate (they do not stall and have encoders built-in for true closed loop accuracy), can run at higher speeds (5000rpm vs 3000rpm max), run more efficiently (drawing power-on-demand vs steppers running 100% current) and thus run cooler (servo motor case temperature lower than step motors) and quieter (step motors are noisy above 15-20rps). Servo motors have feedback with closed-loop operation; as position error increases, the servo system increases the current and torque to the motor to close that error. As an error driven system, it’s more energy and also more thermally efficient. Servo systems are more common for higher power systems and more cost-effective offering a number of newer options than stepper drives (Ethernet tcp/ip communications, Ethernet/IP and other field bus options, USB and Modbus communications) and can be used with Xpress HMIs.
As step motors have very high torque at 0 speed, and 42dimensions, the PV42 gearhead could be used with a servo motor, allowing for high startup torque and additional mechanical advantage of a gearbox.
Stepper applications were traditionally sized for a 50% torque margin where servo motors sized for a 20% torque margin. The Zeta and Gemini Steppers with their advanced smoothing features allowed running closer to the edge of the speed torque curves but many times were used as an upgrade from older stepper drives (S series, A series, etc) that didn't have the performance of the Zeta/Gemini. Checking the motor sizing can confirm the right size motor is being used.
The P-series servo motors have high-resolution absolute encoders built-in that increase stability and make the system easy to tune.
The P-series drive has next generation auto-tuning and most systems out of the box with the default tuning gains don’t even need adjustment, but if it is, it’s single button auto-tuning in the DST software. They can be run into step & direction signal identical to S drives (S6 or S8 drives) or ZETA drives (ZETA8 or ZETA12 or ZETA4-240) requiring no program changes at the PLC or motion controller.
The IPA is a fully programmable servo drive controller. It could be used to replace older SX (SX6 or SX8) or ZETA6000 (ZETA6112, ZETA6108 or ZETA6104-240).
Our local Parker ATCs have automation engineers on staff that can review the loads & speeds and re-size the motor. We'd recommend contacting your local Parker Automation Technology Center (ATC) that can review the application requirements to determine if a servo system is appropriate as replacement and a motor/drive/gearhead (if needed) combination.
