2.5 Analogue to position mode
Acceleration
The acceleration parameter can be useful in systems in which the voltage source instan-
taneously applies a rapid change without any ramp acceleration. Under this condition,
the MAC motor will take care of making a controlled acceleration and deceleration.
Note that no position information is lost if the acceleration is limited. The target position
is always respected and used.
Torque
The maximum torque can be limited in the range 0-300%. 300% corresponds to the rat-
ed peak torque of the MAC motor used.
Load
The Load parameter is the overall gain in the position/velocity filter and ensures that the
motor is stable with the actual mechanical inertia used in the application. See also the
chapter
Servo filter adjustment, page 49 for further details.
Error Handling
Worst case limits for the position range and follow error (maximum position error) can
be set up here. Please consult the chapter
Error messages and error handling, page 36 for
details.
Motor Status
The actual mode, speed, position, position error, load torque, load current, regenerative
energy (energy returned from the motor) can be monitored here.
Inputs
The supply voltage and actual voltage at the analogue input can be measured here.
Homing
In typical gear mode applications the motor is moving relatively without any absolute
zero point but for applications that require a specific mechanical zero position, the gen
-
eral Homing in the MAC motor can be used. Please consult the chapter Mechanical Hom-
ing, page 28.
