Controlled deceleration
Normally, in the event of a power failure or an Emergency-Stop,
the motor coasts to a halt without frequency inverter control. In
some applications, however, it is necessary to control the motor’s
deceleration. This function is provided for such cases.
To use this function, the power supply for connections R0 and T0
must be changed.
By default, terminals R0 and T0 are connected to phases L1 and L3
through connector J51 (a Fig. 162).
For controlled deceleration to work, you must connect terminals
R0 and T0 to DC+ and DC– (a Fig. 163).
Proceed as follows:
X Release the two screws of terminals R0 and T0. Remove
connector J51 with the cable from the circuit board (retain the
plug).
X Connect a cable to terminal R0, which is long enough to reach
terminal DC+ (do not connect yet).
X Connect a cable to terminal T0, which is long enough to reach
terminal DC– (do not connect yet).
X Remove the ferrite rings from the connector cable (J51) and
guide the new cable through the ferrite rings.
X Twist the two cables with each other.
X Connect terminal R0 to DC+ and terminal T0 to DC–.
With this wiring arrangement, the motor can feed the frequency
inverter’s control electronics when the power supply is switched
off.
Warning!
Before working on the DV6, isolate the device from its
power supply. Risk of fatal injury from electrical current.
