Axis name (16 ASCII characters). SMB600 is the first character: "Axis 0"
SMB616 to SMB619 Reserved
SMW620
Axis 0: Error code (See "Axis of Motion error codes" (Page 544) list.)
SMB622 Axis 0: Input/output status: Reflects the status of the inputs and outputs
• DIS (Disable outputs):
– 0 = No current flow
– 1 = Current flow
• TRIG (Stop input):
– 0 = No current flow
– 1 = Current flow
• STP (Stop input):
– 0 = No current flow
– 1 = Current flow
• LMT- (Negative travel limit input):
– 0 = No current flow
– 1 = Current flow
• LMT+ (Positive travel limit input):
– 0 = No current flow
– 1 = Current flow
• RPS (Reference point switch input):
– 0 = No current flow
– 1 = Current flow
• ZP (Zero pulse input):
– 0 = No current flow
– 1 = Current flow
