P73x Brake
function
MOVIDRIVE
®
inverters are capable of controlling a brake installed on the motor. The
brake function acts on the binary output DBØØ which has the fixed assignment of the
'/BRAKE' function (24 V = brake released). In drives with encoder feedback (speed con-
trol), it is possible to select between electrical holding of the load and mechanical appli-
cation of the brake in halt condition.
P730 / P733 Brake
function 1/2
Setting range: ON / OFF
This function determines whether the brake is to be activated when the enable is with-
drawn (enable = "0"). The brake is always active in controlled hoist operation.
