Resolution: 16 bits
Accuracy: ±20 mV (Typ)
Maximum output current: ±10 mA
Settling time (±1%): 1.2 ms (Typ)
Dynamic Brake (DB)
Activated when a servo alarm or overtravel (OT) occurs, or when the
power supply to the main circuit or servo is OFF.
Regenerative Processing
Built-in (An external resistor must be connected to the SGD7S-470A to
-780A.)
Refer to the following manuals for details.
Σ-7-Series Peripheral Device Selection Manual
(Manual No.: SIEP S800001 32)
Overtravel (OT) Prevention
Stopping with a dynamic brake (DB), coasting to a stop, performing a
hard stop, or smooth stop (decelerating to a stop) for a CCW-OT (CCW
Drive Prohibit Input) signal or CW-OT (CW Drive Prohibit Input) signal.
Protective Functions Overcurrent, overvoltage, low voltage, overload, regeneration error, etc.
Utility Functions Gain adjustment, alarm history, jogging, origin search, etc.
