introduction to macros
Unidrive operation can be simplified by using pre-
configured application macros. These macros are held in
the internal memory of the drive and are user selectable.

0 Default mode
1 Easy mode
2 Motorised potentiometer
3 Preset speeds
4 Torque control
5 PID macro
6 Axis Limit control
7 Hoist control/brake release
8 Digital Lock
When a Macro is not enabled, the drive operates in a default
configuration (EURO USA)
Macro 1 – Easy Mode
Easy mode defines the most commonly used
features with only 10 parameters. These parameters
are numbered 0.01 to 0.10

Macro 2 – Motorised Potentiometer
motorised potentiometer within the Unidrive by simply
supplying two logic input signals to increase or
decrease the "potentiometer". The output of the
"potentiometer" may be routed to control any of the
drive's non-bit parameters such as speed, torque or
current limit. The function may be configured to reset
upon power cycling or to memorise its value.
