Program Description
y
Read CR#33, #34 (current position) and CR#35, #36 (current speed).
y
Set up CR#25, #26 for the variable speed operation and D300 as the register (+/-
for the direction).
y
Write K16 (H’10, i.e. b4 = 1) into CR#32 to set up as variable speed operation.
y
Set X0 = On to enable the variable speed operation mode; set X0 = Off to disable
the variable speed operation mode.
y
When X1 = On, the variable speed = 50kHz.
y
When X2 = On, the variable speed = 60kHz.
y
When X3 = On, the variable speed = 70kHz.
y
X1, X2, X3 = Off, the variable speed is fixed at 10kHz.
