Built-in
functions
Overtravel (OT) prevention
The drive slows down and stops when P-OT and N-OT
act.
Protection functions
Overcurrent, overvoltage, undervoltage, overload, main
circuitdetectionabnormal,heatsinkoverheat,power
supply phase loss, overspeed, encoder abnormal, CPU
abnormal, parameter abnormal, etc.
LED display Main circuit CHARGE indicator, 6-digit LED display
Vibration suppression
Four notches that can suppress mechanical resonance
of the 50–4,000 Hz frequency are available on each
axis, with 2 of them allowing adaptive setting. Both
themiddle-highfrequencyvibrationsuppressionlter
(that can suppress mechanical/system vibration of the
30–1,000 Hz frequency) and the low frequency vibration
suppressionlter(thatcansuppressmachinetable/end
vibration of the 1–100 Hz frequency) are available.
Communication protocol Ethernet, EtherCAT
Dynamicbrake
Built-indynamicbrakeforemergencybrakingincaseof
an abnormality
Brakepowersupply
Theoutputofbuilt-inbrakepowersupplymustbe
connected to an external 24 V power supply via the
CN7port.Thebrakecoilcanbeconnecteddirectlyto
theBR+andBR–ports.
