Other Commands
These commands are without writing data and executed by writing the axis assignment and command code into WR0 command
register.
[Note]
•
It requires 125 nSEC (maximum) to access the command code when CLK=16MHz. Please write the next command
after this period of time.
7.8.1
Speed Increase
Code
Command
70
h
Speed increase
This command increases a speed by the value of the speed increasing / decreasing value setting during the driving.
The speed increasing/decreasing value (IV) must be set by speed increasing/decreasing value setting command (15h) in advance.
This command can be used during continuous pulse driving and cannot be used during fixed pulse driving. If this command is
used frequently during fixed pulse driving, premature termination or creep may occur at the termination of driving.
In S-curve acceleration / deceleration driving, this command will be invalid even if written during acceleration / deceleration.
Make sure to use it during constant speed driving (Page1 of RR3 / D5
:
CNST
=
1).
The drive speed setting value (DV) is not updated by this command.
This command cannot be used in interpolation driving.
7.8.2

Command
71
