27 – 486 HEIDENHAIN Service Manual iTNC 530
X150, X151:
Drive controller
enable for
axis groups
Terminal, 9-pin
The connecting terminals X150 and X151 are located on the bottom of the CC 42x (B).
X150 controls drive enabling for the axis groups on the first controller board (PWM outputs
X51 to X56).
X151 controls drive enabling for the axis groups on the second controller board (PWM outputs
X57 to X60 or X62).
X169:
NC supply voltage
and control signals
Ribbon cable connector, 50-pin, same assignment as X69.
See “X69: NC power supply and control signals” on page 27 – 481.
The pin of an axis group must always be wired to the connector on whose PCB the control
loop is located.
If an axis group contains control loops located on both PCBs, then the pins of both
connectors must be wired.
