1936 Connector number for first pulse module
1937 Connector number for second pulse module
[Data type] Byte axis
[Valid data range] 0 to 7
To use a pulse module, this parameter must be set to “connection number
for the pulse module,” minus 1; that is, 0 for connector number 1, 1 for
connector number 2, and so on. It is also necessary to set up bits 6 and
7 of parameter No. 1905. For an axis that does not use a pulse module,
0 is specified for the parameter. Basically, each axis can be combined with
any connector, but the smaller connector numbers must be used first. For
example, connector number 4 cannot be used unless connector number 3
is in use.

If the FSSB setting mode is automatic setting (bit 0 of parameter No. 1902
= 0), this parameter is set automatically when data is entered using the
FSSB setting screen. For manual setting 2 (bit 0 of parameter No. 1902
= 1), the user must set this parameter.
Number Message Description
460 n AXIS : FSSB DISCON-
NECT
FSSB communication was interrupted.
The most likely causes are:
1. The FSSB communication cable is
disconnected or has a broken con-
ductor.
2. The amplifier power supply was
turned off.
3. A low–voltage alarm condition oc-
curred in the amplifier.
461 n AXIS : ILLEGAL AMP
INTERFACE
The fast type interface was assigned to
both axes of a two–axis amplifier.
462 n AXIS : SEND CNC
DATA FAILED
The slave could not receive data cor-
rectly because of an FSSB commu-
nication error.
