Analog monitor output
Monitor output mode
selection
(ch1, ch2)
Used to set the output signal from analog monitor ch1
and ch2 of the servo amplifier.
B: Bus voltage (servo amplifier of
100V/200V: + 8V/400V, servo
amplifier of 400V: + 8V/800V)
Servo forced stop
selection
0: Valid (Use the forced stop
signal.)
1: Invalid (Do not use the forced
stop signal.)
0: 2.25[KHz]
2: 6.375[KHz]
Low acoustic noise mode
selection
Used to set the optional function 1 (Carrier frequency
(Low acoustic noise mode selection) )
• Carrier frequency (Low acoustic noise mode
selection)
20[dB] can decrease the electromagnetic noise
which occurs from servomotor when "1: 9.0[KHz]" is
selection.
3: 9.0[KHz]
Servo adjustment parameters

2
Optional function 1
Serial encoder cable Used to set serial encoder cable selection.
0: 2-wire
1: 4-wire (Supports long distance
cables)
