CAUTION
Possible malfunction caused by inappropriate
holding brake!
⇒
Maximum permissible braking current: 2 A. Note that
the maximum braking current can effect the voltage
output "DC +24 V" at X8 (see page 6-20).
⇒
Do not overload the connection.
⇒
Use only closed-circuit brakes!

CAUTION
Malfunction of the installation caused by
damaged signal contacts!
⇒
Observe the following instructions, in order to avoid
damage to the signal contacts and malfunction of the
installation.
⇒
Do not overload the contact (see Fig. 6-19).
⇒
Do not connect the contactor coils directly to the contacts because of
high short-term currents.
⇒
Do not use varistors to protect the signal contacts.
The Bb1 contact is closed if:
•
voltage was applied at any time at X5/L1, X5/L2, X5/L3 after switching
on the control voltage and
•
all equipment-internal monitoring functions are signaling that they are
in working order.
The drive is then ready for input power (main contactor ON).
The contact opens:
•
in the event of fault.
•
after switching power off, unless the DC bus voltage has dropped
below 250 V.
