What replaces a SX drive?

Note that the SX are no longer repairable. There is no direct replacement for the SX drive. The best drive/controller to replace the SX depends on your application's needs. It would be good to contact your local Parker Automation Technology Center (ATC) to discuss replacement options with our newer products.

The newer IPA servo drive/controller could be considered but the motor would need to be updated to a servo motor. Servo motors are closed loop (no stalls, no lost position), more efficient (draw power on demand not running full power all the time), run cooler and aren't noisy. The IPA has Ethernet communications making it easy to connect and can be run as standalone, has 7inputs/4outputs and can also be controlled via Ethernet/IP from an Allen Bradley PLC. The BE series servo motors are NEMA frame sizes (23 or 34) and have larger shaft diameters because of the higher power. The newer P series motors are metric and could be considered if the mechanics can be updated, such as replacing a mounting kit on a gearhead.

 

 

 

1. Gemini GT6 or GT6K

The Gemini and Gemini6K is good if you want to re-design your application with Parker's most advanced stepper offering.

The Gemini GT6-L5 (5 Amps) or GT6-L8 (8 Amps) supports 31 programs. The SX could have 100 sequences though very few customers used all of them. The Gemini GT6K-L5 (5 Amps) or GT6K-L8 (8 Amps) can have over 100 programs/sequences. For SXF replacements, use GT6K. It is fully digital with motor current setup done via software instead of dipswitches.

The Gemini drive has both a different programming language and different connectors. A GC-50 can give screw terminal access like the old SX, or the din rail mountable GEM-VM50. For the encoder input on the GT6K, the GC-26 can give screw terminal axis.

The Gemini and Gemini6K uses MotionPlanner software which is compatible with Win7 (32 or 64bit) computers. The GT6K also has Ethernet communication, though doesn't ship enabled from the factory (one time activate via serial).

2. ZETA6104 or ZETA6108

The Zeta6104 (4 Amps) or 6108 (8 Amps) is usually the easiest upgrade. Both the Zeta and SX drives run on AC power, are roughly the same physical size, and both have screw-terminal connections. The computational ability of the Zeta61xx is roughly equal to that of the SXF. However, it uses Motion Architect software which is only compatible with Win XP or earlier (not Win7). MotionPlanner can be used with Win7 PCs though.

3. OEM750X

If keeping a similar programming language is the most important thing, consider the OEM750X. It uses a more limited version of Compumotor's X-language. The OEM750X runs on DC power (24-75VDC) and uses one 25-pin connector. It uses XWare like the SX. XWare is only compatible with WinXP or earlier PCs.

4. VIX500IM-DRIVE

The ViX is a programmable stepper drive. It's a DC powered drive (80vdc) so it may not have the top speed of the higher voltage SX (120vac = 170vdc bus voltage). The ViX uses the X language but isn't as full implementation of the X language as the SX. Also note, it uses EasiVsoftware which is only compatible with Win 7 32-bit or WinXP earlier (not Win7 64bit).

SX Motors

The SX was sold with S series step motors. Example, SX83-135 was an SX drive with a S83-135 motor. The motor can still be purchased with a -MO (motor only) at the end of the part number, ie S83-135-MO. This includes the connector at the end of the cable. When ordered together, these shipped wired in series. However, users could change this in the field.

It's the same motor as the ZETA83-135-MO and ES series step motor (in this case, ES33B-DNR10 as it's a 34frame 3stack).
