D/A = maximum D/A voltage
IG = initial gain
These formulas include an allowance for a 127% feedrate override factor.
These formulas apply to both ipm and mmpm.
Jog Rate
The high and log jog rate words (Figure 7.20) specify the speeds at which
you can jog the axis. You can jog the axis only in manual mode. Program
the values in BCD format. The operator can select jog speed (high or
low) by controlling the jog rate select bit in the command block.

This BCD value (0.999 ipm or
19.99 mmpm max) times the
multiplier is the high jog rate. It must
not be higher than the rapid traverse
rate.
