Note
GND_P and GND_D are internally connected in the drive. It is not needed or recommended to duplicate this
connection externally.
9.3.3. Power Supply EMI Filter
In applications that require mitigating conducted and radiated electromagnetic emissions an input EMI filter is
necessary. Depending on the application, motor construction, PWM frequency and specific EMC requirements the
filter should be chosen. The connections are shown next, a good PE plane is strongly recommended. Please follow
. Note that the Everest XCR includes 2 x 1 nF 2 kV capacitors between GND_P and PE
(the drive aluminum enclosure).
For lowest EMC, it is recommended to use a 2 stage filter like TE Connectivity 30EMC6.
9.3.4. Shunt Braking Resistor Connection
A shunt braking resistor can be activated from Everest XCR by using an external transistor. Any of the 4 general
purpose outputs can be configured to turn-on when the dc bus exceeds a certain threshold:
.
The digital outputs provide a 0 ~ 5 V output with a 470
Ω
in series resistance inside the drive. This will typically be
enough to turn on - off a power MOSFET like IRLR3110ZTRPBF. Ensure that a transient voltage Zener like
MM3Z6V2T1G is placed in parallel with the gate of the transistor and a pull-down 10 k
Ω
resistor ensures a safe off
state of the transistor in case of disconnection. If the shunt braking resistor is inductive a re-circulation diode like
V8P10-M3/86A is needed.
