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 catalog for details.
AC Servo Drives
Σ
-7 Series (Catalog No.: KAEP S800001 23)
Overtravel (OT) Prevention
Stopping with dynamic brake, deceleration to a stop, or coasting to a
stop for the P-OT (Forward Drive Prohibit) or N-OT (Reverse Drive Pro-
hibit) signal
Protective Functions
Overcurrent, overvoltage, low voltage, overload, regeneration error, etc.
Utility Functions
Gain adjustment, alarm history, jogging, origin search, etc.
