Name and function
Encoder cable communication system
0: Two-wire type
1: Four-wire type
Incorrect setting will result in an encoder transmission
data error 3 (The servo amplifier not receiving) (16.3).
For the encoder cable communication method, refer to
section 11.1.2.
Selection of servo lock while the servo motor stops in
internal speed control mode.
In the internal speed control mode, the servo motor
shaft can be locked to prevent the shaft from being
moved by the external force.
0: Valid (Servo-locked)
The control to maintain the stop position is
performed.
1: Invalid (Not servo-locked)
The stop position is not maintained.
The control to make the speed 0r/min is performed.
In-position range unit selection
0: Command input unit
1: Servo motor encoder pulse unit
Stroke limit warning (99. ) selection
0: Valid
1: Invalid
When this parameter is set to "1", the stroke
limit warning (99. ) will not occur even if the
forward rotation stroke end (LSP) or reverse
rotation stroke end (LSN) turns OFF.
Tough drive warning (F0.
selection
0: Writing to alarm history: Yes
1: Writing to alarm history: No
The alarm is written to history at the tough drive
warning (F0. ) occurrence when "0" is set.
