Regeneration resistor (optional)
A suitable regeneration resistor may be required to
dissipate excess power from the internal DC bus
during motor deceleration.
The regeneration resistor must have a resistance of
at least 39
Ω
, inductance of less than 100µH, and a
power rating suitable for the application. Baldor parts
RG56 (44W) or RG39 (100W) are recommended.
Connect the regeneration resistor to R1 and R2.

Motor feedback input
The MicroFlex e100 can operate with incremental,
SSI, EnDat or SinCos encoder feedback devices.
The device type is configured in Mint WorkBench.
Suitable cables are available from Baldor.
Connect the motor feedback signal to connector X8.

USB communication
The MicroFlex e100 communicates with the host PC
using USB1.1 communication.
Connect the supplied USB cable between the
MicroFlex e100 and the host PC’s USB port (USB1.1
or USB2.0).
AC power, fuses and filter
MicroFlex e100 can accept supply voltages of
105-250VAC 50/60Hz, 1-phase or 3-phase.
For three phase supplies, connect phases to L1, L2
and L3.
For single phase supplies, connect supply to any two
line inputs, for example L1 and L2.
The AC supply must incorporate a circuit breaker (or
fuse) and the specified filter. For ideal earthing, mount
filter on the same metal surface as MicroFlex e100.
Protective earth must be connected to the
MicroFlex e100 case using an M4 screw in the top of
the metal heatsink.

Motor U V W outputs
Connect the motor to the U, V and W outputs.
The U, V and W outputs must be connected to
their corresponding U, V or W terminal on the
motor. Misconnection may result in uncontrolled
motor movement.
Motor earth should be connected to the
MicroFlex e100 case using an M4 screw in the
top of the metal heatsink.
The motor cable shield should be connected
using a conductive earth/ground clamp,
attached to the same metal surface as the
MicroFlex e100.

24VDC control circuit supply
MicroFlex e100 requires a 24VDC (20-30VDC), 1A supply to power the
control electronics.
Connect the control supply at connector X2.
A fused DC supply should be provided for the MicroFlex e100. If other
devices are to be powered from the same 24V supply, a filter (Baldor catalog
number FI0014A00) should be installed to isolate the MicroFlex e100 from the
rest of the system. Alternatively, a ferrite sleeve may be attached to the supply
cable near connector X2.

Drive enable input
To enable the MicroFlex e100, 24VDC (12-30VDC)
must be applied to the drive enable input.
Connect the drive enable signal to pins 9 and 19 of
connector X3.

Ethernet communication
The MicroFlex e100 receives demand signals and
sends feedback over the Ethernet based ETHERNET
Powerlink (EPL) connection.
Connect a CAT5 Ethernet cable between the
MicroFlex e100 and an EPL compatible controller
such as NextMove e100. Suitable cables are
available from Baldor.
