Macro 6 – Axis Limit control
Using this macro enables two digital inputs to be
re-programmed so providing limit switch lockout for
axis position control systems. The drive would normally
be run from a +/- 10v reference and controlled forward
/ backwards from this. If a limit switch level is reached
the drive will be forced to stop independent of the
speed setting.

Macro 5 – PID control
This macro configures the drive to control a motor
with reference to PID control signal. In PID control, the
error resulting from differences between the PID
feedback and PID reference is passed through a limiter,
a scaling stage and finally the error is added to the
frequency / speed signal.
