Release Speed [33D]
The release speed only operates with the brake function:
brake release [33C]. The release speed is the initial speed
reference during the brake release time. The torque reference
is initialized to 90% of T
NOM
to ensure that the load is held
in place.
Communication information
Brake Engage Time [33E]
The brake engage time is the time the load is held while the
mechanical brake engages. It is also used to get a firm stop
when transmissions, etc. cause “whiplash” effects. In other
words, it compensates for the time it takes to engage a
mechanical brake.
Communication information
Wait Before Brake Time [33F]
The brake wait time is the time to keep brake open and to
hold the load, either in order to be able to speed up
immediately, or to stop and engage the brake.
Communication information
Vector Brake [33G]
Braking by increasing the internal electrical losses in the
motor.
Communication information
Brake Fault trip time [33H]
The “Brake Fault trip time” for “Brake not released”
function is specified in this menu.
Communication information
The “Brake not engaged” warning is using the setting of
parameter “Brake Engaged time [33E]”.
