Communi-
cations
Function
Digital Operator
Connect the Σ -V digital operator (model: JUSP-OP05A-1-E) through an
applicable analog monitor unit (model: JUSP-PC001-E) and a connection
cable (model: JZSP-CF1S05-A3-E), or a relay cable (model: JZSP-CF1S00-
A3-E).
Personal Computer
Communications (USB)
Supports SigmaWin+.
Based on the USB 1.1 standard (12 Mbps).
LED Display ALM (red), RDY (green)
Analog Monitor
Number of points: 2
Output voltage:
± 10 VDC (linearity effective range ± 8 V)
Output through the analog monitor unit (model: JUSP-PC001-E), the connec-
tion cable (model: JZSP-CF1S05-A3-E), and the analog monitor cable
(model: JZSP-CA01-E).
Dynamic Brake (DB) Not supported.
Regenerative Processing Not supported.
Overtravel Prevention (OT) Deceleration to a stop or free run to a stop at P-OT or N-OT
Protective Function Overcurrent, overvoltage, overload, and so on.
Utility Function Gain adjustment, alarm history, JOG operation, origin search, and so on.
