Variable Speed Operation and Dupli-
cated Specifications for Various Opera-
tion Modes
[7] Variable speed operation
• When the operation command BFM #25 b12 is set to
1, the speed pulses specified in the BFMs (#20 and
#19) are generated.
• This operating speed can be freely changed even
while pulses are generated. However, because
there is no cushion start/stop function, acceleration
and deceleration must be controlled by the PC.
• Only b0 (error reset) and b12 (variable speed
operation) of the operation command BFM #25 are
valid in this mode. Set b1 to b11 to 0.
When b12 is set to 1, variable speed operation is
performed.
When b12 is set to 0, pulse output is stopped.
• As for the parameter BFM #3, only b1 and b0
(system of units) and b8 (pulse output format) are
valid.
• The rotation direction (forward or reverse) can be
specified by the sign (positive or negative) of the
speed command (BFMs #20 and #19).

When the bits which determine operation modes such
as b4 to b6 and b8 to b12 are turned on simultaneously
in the operation command BFM #25, any operation is
not executed.
If an other mode input is turned on while operation is
being performed in any mode, such an input is
neglected.
