18.1.3 Troubleshooting

To find out, whether the connected encoder or the interface of the control is defective, the
interchange method can be used. Use the interface of a working axis for this purpose.
Error in X axis. position encoders connected to MC
Example
Example machine
parameters MP 100.x = CZYX (X = 1st axis, Y = 2nd axis, Z = 3rd axis, C = 4th axis)
MP 110.0 = 1 (X-axis at X1 input)
MP 110.1 = 2 (Y-axis at X2 input)
MP 110.2 = 3 (Z-axis at X3 input)
MP 110.3 = 4 (C-axis at X4 input)
MP 115.0 = %0000000000 (all inputs 1 Vpp)
MP 115.1 = %0000000000
MP 115.2 = %0000000000 (all inputs 50 kHz)

Caution
For trouble shooting do not connect obviously defective controls (e.g., position encoder with
short circuit after entering of humidity) to other interfaces (e.g., X1-X6, X35-X38) of the
control.
Note
Always switch both the cable and the interface assignment by machine parameter!
Note
MC:
Position encoder inputs can be assigned in any order.
CC 424 (B):
On the main DCB and on the auxiliary DCB the position encoder inputs can be assigned in
any order.
