The RTA Pavia GMD‑04 is a 95–130 VDC stepper‑motor drive capable of 5–12 A output and supports microstepping (200/400/800 steps) via dip‑switches, with an optional RMM36 frequency card. Common failure points on this class include over‑current protection trips, winding insulation breakdown, and power‑stage MOSFET degradation; the drive’s internal regulator can also fail under prolonged high‑temperature operation. First‑check diagnostics: verify input voltage and current limits against spec, inspect the PCB for burnt or cracked components (especially MOSFETs and heat‑sink connections), and review any fault codes or LED status indicators on the unit.[oss-gpt-20b] |
