The PD42-3-1370-TMCL is a PD-1370 series PANdrive smart stepper motor integrating a NEMA 17 (42 mm) motor with the TMCM-1370 controller/driver electronics and a magnetic encoder for position feedback and optional closed‑loop control. It operates from 9 to 28 VDC and supports up to 2 A RMS (2.8 A peak) phase current with up to 256 microsteps. Features include an RS485 interface using TMCL protocol, integrated s‑shaped and SixPoint motion ramp controller, SpreadCycle current control, StallGuard2 load detection, and CoolStep automatic current scaling. The PD42-3 variant provides 0.44 Nm (44 Ncm) holding torque and a body size of 42 mm × 42 mm × 60 mm (exclude 24 mm shaft).
