3.24 Connecting the motor power modules (only CC 61xx)
The iTNC 530 HSCI is connected with HEIDENHAIN or non-HEIDENHAIN
inverters through a PWM interface.
For a description of the HEIDENHAIN inverter systems, refer to the Technical
Manual "Inverter Systems and Motors." The components required for
operation of the iTNC 530 HSCI with non-HEIDENHAIN inverter systems are
described in the manual "Technical Information for the Operation of
SIMODRIVE and POWER DRIVE Inverter Systems." The individual PWM
outputs of the CC 61xx are assigned to different controller groups.
The following applies to the output signals to the power module:
Logic level: 5 V
Analog signals I
ACTL
: ±7.5 V
PWM frequency: Can be set at
3333 Hz, 4166 Hz, 5000 Hz, 6666 Hz,
8333 Hz and 10000 Hz
X51 to X56:
PWM output
Pin layout:
For more information on the controller groups of the CC 61xx, see page 1067.

The interface complies with the requirements of EN 61800-5-1 for
"protective extra-low voltage" (PELV).
