IndraMotion MTX micro Easy Setup for Standard Turning and Milling Machines
Spindle motors of type MAD can be connected to connecting points X5.1 and
X5.2. These motors provide maximum convenience on commissioning be‐
cause the parameters are already saved in the motor encoder and are read
in automatically.

● An encoder connection point X4 and a temperature monitor‐
ing connection point X6 are automatically allocated to each
motor connection point X5. The following applies: X5.1 →
X4.1 → X6.1, X5.2 → X4.2 → X6.2
● We strongly recommend that you use the Rexroth encoder
cable RKG4200 for connecting the motor encoder.
● We also strongly recommend that you use the Rexroth mo‐
tor cable RKL for connecting the motors. The shield is con‐
nected via the shield connection points XS2 (tube clips).
● The maximum length of the connecting cables is 40 m. The
maximum length of the connecting cables must not be ex‐
ceeded.
● Contacts 3 and 4 of terminal X6 are provided for activating
an external spindle brake. Please comply with the instruc‐
tions in
page 55.
Connection points X5.1 and X5.2 allow operation of standard asynchronous
motors as spindle motors in encoderless mode (open loop). This is achieved
by the integrated frequency converter function of the HC*02.
