Technical Specifications of the Drive Circuit

Commercial stepper motor power sections can be connected to the drive circuit of
the IP 267. The "Clock" (TN) and "Direction level" signals can be operated both
with 5 V (internal) or with a special voltage of V
allows you to operate power sections with both 5 V differential inputs (RS 422) or
logic inputs in the range 5 V to 30 V. You can set the desired voltage type with the
sliding switch on the frontplate. The special voltage V
2 to 9 on the terminal block ( 3.3). The output signals (clock and direction level)
are available inverted and non-inverted and the drive circuits are current-limited.
