DF9201893-A0N Product Technical Manual

Manufacturer: Yaskawa / Motoman

Model: DF9201893-A0N

Board Alias: JANCD-MSV01B (Safety Revision)

Product Type: 4-axis safety servo control board / motion control card for robot controller

Compatible System: Motoman DX200 Controller 

I. Product Overview

DF9201893-A0N is a 4-axis safety servo control board specifically for the Yaskawa DX200 controller. It is an enhanced version of DF9201893-A0 with safety functions (N represents Safety).

The core is used for the servo drive of the robot body + external axes (tool changer, traveling axis) for safe motion control. On the basis of the basic servo control capability, it integrates dual-channel safety circuits, safety torque shutdown (STO), safety stop 1 (SS1), safety speed limit (SLS), etc., meeting SIL2 (IEC 61508), PLd (ISO 13849-1) safety levels, suitable for high-safety requirement automated production lines in automotive welding, stamping, handling, etc.

II. Version and Compatibility (A0N vs A0)

1. Core Differences

DF9201893-A0: Basic standard version (non-safety type)

No safety functions, only basic servo control

Safety level: None (standard industrial level)

DF9201893-A0N: Safety enhanced version (N = Safety)

Integrated dual-channel safety monitoring circuits

Support STO, SS1, SLS, SBC safety functions

Safety certification: SIL2, PLd, Cat.3

Dual-channel redundant encoder/driver signals
