Term Meaning
BaseUnit The BaseUnit carries the StepDrive technology module and
represents the contacting for wiring.
Boost current Higher motor torque is required for acceleration and decel-
eration of a stepper motor compared to the torque at aver-
age and slew velocity (f
MAX
). With a phase current setting
adjusted for rapid acceleration and deceleration (steep
ramps), the current is higher than needed while at constant
velocity. The motor will heat up faster than with the rated
current applied. With a lower phase current, it is only possi-
ble to accelerate or decelerate with correspondingly longer
ramp times.
Therefore, it is recommended to select different current set-
tings for acceleration/deceleration and slewing:
– Continuous/slewing: Run current
– Acceleration/deceleration: Boost current
Data record List of parameters
Various presetting such as frequencies, acceleration ramps
or waiting times are required, which are referred to as pa-
rameters to operate the controller.
Basic parameters are stored at delivery with which the con-
troller can be operated in many applications.
DIS input Input DISABLE:
It disables operation with external signal present.
Direction This signal determines the direction of rotation of the motor:
If the bit is set, the motor rotates in negative direction. If the
bit is not set, the motor rotates in positive direction. The sig-
nal may only be changed if the stepper motor is at a stand-
still or driven at a velocity within the start/stop range. The
signal must not change 1 µs before the clock signal until 4
µs after that. Switching the direction of rotation at higher
speed leads to step failure or standstill of the motor.
ET 200SP-Station Distributed, multi-modular and micro modular I/O system
with different interface modules (also with CPU functionality)
for connection to PROFIBUS or PROFINET. Power supplies,
digital, analogue and other technology modules, such as I/O-
mastering and motor starters can be connected.
