QuickSilver Controls, Inc. introduces a low cost CiA DSP 402 CANopen servo motor controller. The SilverDust IGK is a stand alone, single axis controller that includes serial communications (RS-232, RS-485), CANopen and 7 I/O. CANopen can be configured for peer-to-peer, master or slave which allows the controllers to share I/O with other CANopen controllers and 3rd party CANopen devices (i.e. I/O blocks, encoders,…).
CiA DSP 402 refers to CAN in Automation (CiA) Draft Standard Proposal (DSP) 402 CANopen Drives and Motion Control Device Profile. This profile defines such functions as start-up and homing techniques as well as motion profiles. A host controller, for example a PLC, supporting CiA DSP 402 could command multiple CiA DSP 402 motor controllers from multiple vendors. CiA DSP 402 runs on top of CANopen (CiA DSP 302 v4.0).
The RS-232/RS-485 serial network runs in parallel to CANopen for supervisory control from a host (i.e. PC, PLC, HMI..).
The IGK is designed to servo QuickSilver’s NEMA 17 and NEMA 23 frame I-Grade servo motors. 7 bi-directional I/O can be broken out using one of our QCI’s basic breakouts (QCI-BO-B, QCI-BO-B1, QCI-BO-B1A) or, if 24V I/O is needed, using the QCI-BO-B52.
QuickSilver Solves Tightening Applications

The most common tightening applications are caps or nuts. These types of applications require accurate control of torque and position to avoid stripping, under tightening, over tightening, missing bottles, cross-threading, and mechanical jams.
QuickSilver’s programmable single axis servo motor controller can be pre-loaded with the expected/nominal torque profile. If more or less torque is detected for a given position, a fault can be generated notifying the operator of the problem.
QuickSilver’s high torque, direct driver brushless servo motors are ideal for this type of application. Available in NEMA 11, 17, 23 and 34 frame sizes to cover most tightening needs. They have superior holding torque over traditional servo motors which gives them the advantage when “snugging” down those caps or nuts.
For even more torque control, the servo motor controllers are capable or reading in an analog voltage from a load cell or torque sensor and use it to fine tune the motor’s torque.

QuickSilver OEM Servo Motor Controller with CANopen

QuickSilver has added a CANopen option to its OEM servo motor controller. CANopen may be configured for peer-to-peer, master or slave. This allows the controllers to share I/O and registers with other CANopen enabled SilverDust™ controllers or 3rd party CANopen devices (i.e. I/O blocks, encoders, PLCs…). For a multiaxis system, connect several IG-Js, make one the master and let the others receive motion commands over CANopen.
The IG-J1 supports the CAN in Automation (CiA) CANopen Drives and Motion Control Profile 402 which allows master CANopen devices, such as PLCs, to communicate using a standard set of motion commands.
This servo controller is designed to drive QuickSilver’s line of I-Grade NEMA 17, 23 and some 34 frame motors generating from 21 oz-in (0.15Nm) to 300 oz-in (2.1Nm) continuous torque. It also includes serial communications (RS-232, RS-485), and 7 I/O. The RS-232/RS-485 serial network runs in parallel with CAN for supervisory control from a host (i.e. PC, PLC, HMI..).
The 7 bi-directional I/O, 12V-48V input power, and communications signals are accessed through the DB15HD port and can be converted to terminal strips using one of the popular breakouts (QCI-BO-B, QCI-BO-B1, QCI-BO-B1A, or QCI-BO-B52).
