EMotion
Product Introduction
EMotion is a high-performance 4-axis pulse-command type axis card that combines the advantages of the classic NI 7390 and NI 7354 axis cards. It provides high-speed pulse output up to 8MHz per axis, suitable for high-precision platform positioning control, especially in semiconductor equipment.
The 10MHz encoder reading speed prevents step loss during high-speed movement. All input/output front-end circuits feature channel-to-ground isolation to protect the controller from lightning and static electricity in industrial environments. It supports S-curve and Jerk setting functions to reduce vibration during transfer, and provides linear, circular, and helical interpolation functions for various machine tools and processing equipment.
WPC's LabVIEW version continues the design philosophy of NI Motion, making it an ideal alternative for NI axis cards. Since 2021, the addition of Motion Express VIs allows users to quickly get started and develop motor control programs in a short time.

Dimensions
EMotion's dimensions are 254.2 × 147.4 (mm) in length × width; the height without breakout boards is 26.7 (mm).
System Installation
EMotion can be installed directly on a DIN rail; note that the DIN rail clip will lift the body by approximately 12.9 (mm). A clearance of 50 (mm) above the breakout boards is recommended for SCSI cable bending.
System Wiring
EMotion requires an external 24VDC power supply; please use the original WPC ATX-2P power module. Only an RJ-45 Ethernet cable is needed between the controller and the computer; servo drivers and limit switches are interfaced via breakout boards.
If using a specific breakout board, you can connect directly to the driver using a dedicated SCSI cable, greatly simplifying wiring. If using a general breakout board, wire according to the signal definitions.
Breakout boards feature a 24VDC power output function, which can directly power limit switches, eliminating the need for extra wiring and simplifying system complexity.
