Brake to
Stop
This method uses DC injection of the motor to Stop and/or hold the
load.
1.
On Stop, 3 phase drive output goes to zero (off)
2.
Drive outputs DC voltage on the last used phase at the level
programmed in DC Brake Level (158). This voltage causes a
“stopping” brake torque. If the voltage is applied for a time that is
longer than the actual possible stopping time, the remaining time
will be used to attempt to hold the motor at zero speed.
3.
DC voltage to the motor continues for the amount of time
programmed in DC Brake Time (159). Braking ceases after this
time expires.
4.
After the DC Braking ceases, no further power is supplied to the
motor. The motor may or may not be stopped. The drive has
released control.
5.
The motor, if rotating, will coast from its present speed for a time
that is dependent on the mechanics of the system (inertia,
friction, etc).
