Overcurrent error
Overcurrent occurs if the motor current measured in the motor windings is twice as high as it should be (e.g. short
circuit).
Status of the drive
The status of the drive is only shown when SDC information is enabled. The drive bit is 1 when the following
conditions are met:
•
Motor turned on (see "Motor current")
•
Ground fault detection is complete and ok
•
MotorID measurement is complete
•
Motor is supplied with current
•
Motor settling time has passed
•
Supply voltage is in the valid range
•
No overtemperature fault
•
Preset position value is valid (see "SDC life sign monitoring")

Name:
Motor1Step0
This registers is used to specify the number and direction of steps that should be carried out by the module during
the next X2X cycle.
The value is specified with a resolution of: 1/256 of a full step (corresponds to 8-bit microsteps).
The direction of movement is derived from the value's sign:
