3.8.2.17 Torque Enable for QVN Axes: %W34.L<br />

The bits of %W34.L are initialised with 0.<br />

Variable Mnemonic Description<br />

%W34.7 DISC_TRQ31 Torque enabled on QVN axis No. 31<br />

to %W34.0 to DISC_TRQ24 to Torque enabled on QVN axis No. 24<br />

Set to enable torque<br />

Reset to inhibit torque<br />

%W35.7 DISC_TRQ23 Torque enabled on QVN axis No. 23<br />

to %W35.0 to DISC_TRQ16 to Torque enabled on QVN axis No. 16<br />

Set to enable torque<br />

Reset to inhibit torque<br />

%W36.7 DISC_TRQ15 Torque enabled on QVN axis No. 15<br />

to %W36.0 to DISC_TRQ8 to Torque enabled on QVN axis No. 8<br />

Set to enable torque<br />

Reset to inhibit torque<br />

%W37.7 DISC_TRQ7 Torque enabled on QVN axis No. 7<br />

to %W37.0 to DISC_TRQ0 to Torque enabled on QVN axis No. 0<br />

Set to enable torque<br />

Reset to inhibit torque<br />

3.8.2.18 Speed Reference Enable for QVN Axes: %W38.0<br />

Variable Mnemonic Description<br />

%W38.0 DISC_SDP Speed reference enable for QVN axes<br />

Set to enable normal operation of QVN axes.<br />

Reset to cancel the speed reference immediately on the QVN axes to enable<br />

braking at maximum torque.<br />

If the speed references are inhibited, they are forced low.<br />

At power on, the speed references are inhibited.<br />

In the case of detection of a CNC error causing E_CNPRET to go low, the speed reference is forced low for the QVN<br />

axes. Cancellation of the error by a reset again allows the automatic <strong>control</strong> <strong>function</strong> to enable or inhibit the speed<br />

references.<br />

REMARK It is recommended to inhibit DISC_SDP on an emergency stop and to activate a feed<br />

stop so as not to generate an excessive following error.<br />
