Setting Up a Coordinate System
269
Each coordinate system has a variable Isx93 that contains the address of the register that the coordinate
system uses for its time base. With the default value of Isx93, the coordinate system gets its time base
information from a register that is set by % commands from the host computer. A %100 command puts a
value equal to I10 in this register; a %50 command puts a value equal to I10/2 in this register.

Note:
A motor that is not assigned to any coordinate system uses Coordinate System 1’s
time base value for executing its jogging and homing moves. To use another base
value, assign the motor to a different coordinate system, even if there is no need to
write a motion program to run this motor.

Regardless of the source of the time base information, a % query command cause PMAC to report back the
value of the present time base expressed as a percentage of I10.

Time base information can come from other sources. The most common alternative to command-sourced
time base is external frequency-sourced time base, in which the time base value is proportional to the
frequency of a master encoder. This provides a powerful position-synchronized slaving mechanism that is
commonly called electronic cam.
