YASKAWA V1000 Technical Manual

• An external circuit should be added to ensure the brake is fully applied in case of a fault or emergency condition.
• An additional external circuit should also be added
to ensure the brake releases properly when an Up/Down Command
is entered.
When changing the speed using an analog signal, make sure that the source of the frequency reference is assigned to the
control circuit terminals (b1-01 = 1).
A sequence to open and close the holding brake appears in the diagram below.
