− NextMove e100 Motion Controller.

− MicroFlex e100 Servo Drive.

− BSM motor with either encoder, SSI, Endat, Sin/Cos or BISS feedback.

− PC running Windows 2000, XP or later.

− Motor feedback cable terminated with suitable connectors at both ends.

− Motor power cable with a suitable connector at the motor end.

− Mains supply to the MicroFlex e100.

− 24V supply for the NextMove e100 and MicroFlex e100 logic supply and enable signal.

− USB cable.

− EPL Cable between the NextMove e100 and MicroFlex e100.

The minimum wiring configuration between drive and motion controller requires 24V connected to the MicroFlex e100 drive enable

input. This enable signal can be wired via safety interlocks as require. This input is not a safe torque off input – users should ensure

that safety risks are assessed and the design of the safety critical elements of the control system is suitable (e.g. it may be

necessary to include motor contactors between the e100 drive and the BSM servo motor). Further wiring details are available in the

MicroFlex e100 Installation Manual MN1942.

Three digital inputs on the MicroFlex e100 are provide to allow connection of signals such as home sensor and limit switches. Two

of these (Inputs 1 and 2) can be used for high speed registration, capturing position in the order of nS to µS (depending on

feedback type). An additional input provides a hardware enable interlock. Two digital outputs can be configured for functions such

as motor brake control and drive ready.

Drive enable signal:

Each MicroFlex e100 drive needs to have a 24V signal applied to its enable input. This should not be wired from an output on the

NextMove e100 controller (only local axes require the connection of an output on the Nextmove e100). It may be a good idea to

wire the enable signal through a safety relay associated with a guard switch or Emergency Stop circuit (as well as including other

safety measures, such as motor contactors, depending on the level of risk associated with the control system).

Home input:

Home input:

The MicroFlex e100 and MotiFlex e100 differ from other drives in that the homing switch must be wired back to one of the drive’s

digital inputs. The reason for this is that e100 drives perform the home sequences themselves (to ensure maximum accuracy). If the

NextMove e100 tried to track the axis position during homing there would be an error introduced due to delays in the EPL network..

Most of the Mint commands associated with homing are saved as parameters settings on board the e100drive. These settings can

be changed from the NextMove e100 if required using a technique called “re-direction” which is explained later in the section on

homing.

Fast latching inputs:

Triggering a position capture on an input needs to be able to respond in the order of µS. EPL network delays preclude using the

NextMove e100 to capture the position of remote axes. As a result, fast latching triggers must be wired to the MicroFlex e100. Most

of the Mint commands associated with fast latching are saved as parameters settings on board the drive. They can be changed

from the NextMove e100 using re-direction.

The MicroFlex e100 has 2 digital outputs that can be used to control a motor brake. Most of the Mint commands associated with

brake control are now saved as parameters settings on board the drive. They can be changed from the NextMove e100 using re-

direction.
