Servo vision CO.,LTD




The SPiiPlusNT (Network Controller) is designed for incorporation in the MC4U. Once plugged into an MC4U, the MC4U becomes MC4Unt, an EtherCAT master that can manage an EtherCAT network with up to 32 axes of motion and countless number of I/Os and sensor modules. The SPiiPlusNT also includes Servo Processors for controlling local drives that reside in the same MC4Unt enclosure. Like all SPiiPlus products, the SPiiPlusNT uses the same ACSPL+ high level programming language and is supported by the same set of software tools such as the SPiiPlus MMI Application Studio and API for host application development.

The  SPiiPlusDC  (Drive  Controller)  is  also  designed  for  incorporation  in  the  MC4U.  Once  plugged  into  an  MC4U,  the  MC4U becomes MC4Udc that is an EtherCAT slave capable of controlling up to 8 drives and axes. The SPiiPlusNT Master generates the motion trajectories for all the axes, transmitting the data over the EtherCAT network, and the SPiiPlusDC executes the real-time control of the drives and axes.

Network Modules

SPiiPlus UDMnt

SPiiPlus UDMnt (Universal Drive Module) is offered as one and two axis drive for AC Servo motors, DC brush motors, two, three and five phase step motors operating also in close loop.  It operates with motor voltage up to 60Vdc and with 5A or 10A peak motor phase current.

SPiiPlus SDMnt

The  SPiiPlus  SDMnt  (network  Stepper  Drive  Module)  line  of  four  and  eight  axis  open  loop  step  motor  drives  modules  are designed to address the needs of industrial machines for economical and simple  multi-axis motion control solutions. Each unit includes one 36Vdc/3A bipolar drive. All other are 36Vdc/3A unipolar drives. The current level and the micro-step resolution are individually programmable for each drive. The SPiiPlus SDMnt includes two sets of Pulse/Direction inputs and two sets of Pulse/Direction outputs for Master-Slave operation. In addition, there are 6 general purpose inputs and 6 general purpose outputs.

SPiiPlus PDMnt

The SPiiPlus PDMnt (network Pulse/Direction Module) provides the ability to add up to four step motor and servo motor drives with Pulse/Dir interface to an EtherCAT network using any of ACS’ EtherCAT masters. Each of the drive interfaces consists of Pulse/Dir, limit switches, enable and fault feedback. The maximum pulse rate is 4MHz. The module can also be used by a SPiiPlus EtherCAT master to control Laser generators with a dynamically programmable pulse rates.

SPiiPlus IOMnt-32-32

The SPiiPlus IOMnt-32-32 (Network Inputs and Outputs Module) is an EtherCAT digital I/O module with 32 inputs and 32 outputs. The input voltage is 24Vdc
