3.21 Starting lockout in KDA/TDA
For safety reasons, the main spindle should be stopped when setting-
up machine tools. INDRAMAT main spindle drives are thus fitted with
a starting lockout.
• The modular system's main drive remains selectively and reliably shut
down.
• Disconnection is safe, even if the electronics malfunction, since the
opto-couplers are switched off and the power bridge is inhibited.
• Even with defective power transistors, no rotating field can be generated
with an active starting lockout.
Note:
If the AS control input is at 0, the display shows DISABLED and the
starting lockout is activated.
If the AS control input goes from 0 to 1, the controller enabling signal must
be applied once again (RF control input goes from 0 to 1) in order to start
the drive.
3. Controller Functions
If the starting lockout is active, the READY signal output goes to 0. The
Bb potential-free contact remains closed so that the other control units
of the drive package are not shut down.
Safety note: Remove connector plug from terminal strip X2 to
ensure that the AS input is set to 0. The starting lockout (AS)
does not meet personnel safety requirements in the vicinity of
the main spindle!
