A secondary drive can be connected to a pair of differential outputs. The secondary driver will operate off
of the differential output pair 15 and 16 (I/O pair 13 and 14 can also operate in this mode). Setting the
ratio mode to TRUE (1) for the differential output clock (IOS) specifies a secondary drive function. Then
when ratio mode is enabled (
RATIOE ); the secondary axis will follow the primary axis with the ratio
specified by the RATIO variable.
The sequence of commands used to make this setup function would be as follows:
‘Set IOS 15 to step/direction clock type, and ratio mode
IOS 15 = 5,0,1,0,2,1
‘Set IOS 16 to step/direction clock type, and ratio mode
IOS 16 = 6,0,1,0,2,1
‘Set Ratio Mode Enable Flag to TRUE (1)
