* The coefficient of speed fluctuation for load fluctuation is defined as follows:
MECHA-
TROLINK-III
Communi-
cations
Communications Pro-
tocol
MECHATROLINK-III
Station Address
Settings
03h to EFh (maximum number of slaves: 62)
The rotary switches (S1 and S2) are used to set the station address.
Extended Address
Setting
Axis A: 00h, Axis B: 01h
Transmission Speed 100 Mbps
Transmission Cycle
250 μs, 500 μs, 750 μs,
1.0 ms to 4.0 ms (multiples of 0.5 ms)
Number of Transmis-
sion Bytes
32 or 48 bytes/station
A DIP switch (S3) is used to select the transmission speed.

Regenerative Processing Built-in
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.
Applicable Option Modules None
