Pacific Scientific 6410 Stepper Driver Repaired with our 3 Year Warranty

ERD repairs Stepper Driver like this one made by Pacific Scientific as well as all other Industrial Electronics. We also offer a same day quote on all our repairs.

Danaher Motion’s Pacific Scientific 6410 converts step and direction inputs into motor winding currents to control a two phase stepper motor. Principal features include microstepping and mid-band instability compensation for high resolution and smooth operation through both the low speed and midband resonance regions. The output current of the 6410 is DIP switch selectable from 5A RMS (7.1 A PEAK in microstep mode) to 0.625 A RMS (0.88 A PEAK in microstep mode). The drive supplies regulated phase currents for supply voltages between 24 and 75 VDC. It is designed for use with Danaher Motion’s line of hybrid stepping motors and will work with either the standard line or the enhanced performance line.

ERD repairs and refurbishes a complete range of OEM industrial electronic equipment, from basic boards to complex robotics, and will evaluate and quote your unit on the same day.

Quipp 4148 Pacific Scientific 5630 Stepper Motor Drive From Quipp Series 400 Newspaper Stacker Repaired By ERD Ltd with our 3 Year Warranty

This unit is an Quipp or Pacific Scientific (similiar unit with different names) stepper motor drive from a Quipp Series 400 Newspaper Stacker that was fully rebuilt under our 3 Year Warranty Repair program.  This stepper drive was completely rebuilt from top to bottom and the major failures were problems in the power supply and burned outputs.  After repair we hooked up the Quipp to a load stepper motor (we have 100’s of test motors) and tested it fully as shown in the video. This particular repair took 10 days to complete.

At ERD we offer full support for all types and brands of stepper controls including and these were some of the first motor controls we repaired in 1995.

Additionally ERD has repaired 1000’s of items from major newspapers and various types of presses.

From Man Roland to Mitsubishi and Goss – ERD has an extensive track record with over 100 Newspaper’s. (Washington Post – LA Times – Houston Chronicle – Chicago Tribune)
