88 Functional Description Emotron AB 01-4429-01r2
Release Speed [33D]
The release speed only operates with the brake function:
brake release [33C]. The release speed is the initial speed ref-
erence 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 immedi-
ately, or to stop and engage the brake.
Communication information
Vector Brake [33G]
Braking by increasing the internal electrical losses in the
motor.
Communication information

Menu with all parameters for settings regarding to speeds,
such as Min/Max speeds, Jog speeds, Skip speeds.
Minimum Speed [341]
