110 Application macros
Hand/Auto Speed control applications where switching between two control devices is
needed. Some control signal terminals are reserved for one device, the
rest for the other. One digital input selects between the terminals (devices)
in use.
PID control Process control applications, for example different closed loop control
systems such as pressure control, level control and flow control. It is
possible to switch between process and speed control: Some control
signal terminals are reserved for process control, others for speed control.
One digital input selects between process and speed control.
Torque control Torque control applications. It is possible to switch between torque and
speed control: Some control signal terminals are reserved for torque
control, others for speed control. One digital input selects between torque
and speed control.
User The user can save the customized standard macro, ie the parameter
settings including group 99 START-UP DATA, and the results of the motor
identification run into the permanent memory, and recall the data at a later
time.
For example, three user macros can be used when switching between
three different motors is required.
