DB (Dynamic Brake)
[Configuration]
DESCRIPTION:
The DB command (Dynamic Brake) is used to set or disable the dynamic brake function of the Legend
Amplifier. When Dynamic Braking is enabled, a relay inside the amplifier shorts the motor winding
together to absorb energy from the load quickly in an E-Stop situation. More specifically, when the
power is removed from the main power input or the servo is disabled (MO) motor off, the dynamic brake
function is automatically enabled if the DB command is set.
ARGUMENTS: DB x, y, z, w or DBX=x or DB a, b, c, d, e, f, g, h where
x, y z, w, or a, b, c, d, e, f, g, h are either 0 or 1.
