4.7.2 Starting up the axes
Overview
The SINUMERIK 802C has up to three stepper motor feedrate axes (X, Y
and Z). The stepper motor drive signals are output at connector X7 for the:
S
X axis at pins 1–3 (PULS1, DIR1 and EN1)
S
Y axis at pins 4–6 (PULS2, DIR2 and EN2) and for the
S
Z axis at pins 7–9 (PULS3, DIR3 and EN3).
Simulation/stepper motor drive
Setpoint output and pulse feedback can be switched between simulation and drive operation
using the axis MD 30130_CRTLOUT_TYPE and 30240_ENC_TYPE.
Table 4-12
MD Simulation Normal Operation
30130 Value = 0
To test the axis, the actual value is fed
back internally as an actual value. No set-
point output at connector X7. Value = 2
The setpoint signals for stepper motor
operation are output at connector X7. Real
axis traversal is possible using a stepper
motor.
30240 Value = 0 Value = 3
Internal pulse feedback from setpoint out-
put to actual value input “ON”
