Parameter No. 1905
No. 7 6 5 4 3 2 1 0
1905 FSBM2 FSBM1 FSBSL
Data Type: Bit Axis
Parameter Setting Description
FSBSL 0 The servo data transmission interface is Fast type.
1 The servo data transmission interface is Slow type.
FSBM1 0 The first pulse module is not used.
1 The first pulse module is used.
FSBM2 0 The second pulse module is not used.
1 The second pulse module is used.
Note
When parameter No. 1902#0=0, these bits are set automatically. When
parameter No. 1902#0=1, these bits must be set manually. When using the
pulse module, you must also set the connector number for parameter No. 1936
and 1937.
Interface Type
There are two types of interface (Fast and Slow) for transferring servo data. Each type must
accept all of the following conditions:
• For a one-axis amplifier, either type (Fast or Slow) is accepted.
• For a two-axis amplifier, a combination of Fast-Fast cannot be used. Use Fast-Slow, Slow-
Fast, or Slow-Slow.
• For a three-axis amplifier, the first and second axes are applied to a two-axis amplifier, and
the third axis is applied to a one-axis amplifier.
• The axis whose value of parameter No. 1023 is odd uses the Fast type interface.
• The axis whose value of parameter No. 1023 is even can use only the Slow type interface.
• The EGB work axis, the learning control axis, the 125 µs current loop control axis, and the
high-speed interface axis can use the Slow type.
