Oriental Motor USA is pleased to announce the introduction of the CRK Series 5-phase stepping motor and driver package with a built in controller. The CRK Series with built in controller is a compact, space saving 5-phase stepping motor and driver package with a powerful, feature-rich controller built in.

The driver supports stand alone or RS-485 communications with multi-drop capability for network operation and I/O control. Oriental Motor developed this product based upon the request of our customers for an integrated “Stand-alone” driver controller that is cost effective and can easily be networked. Utilizing the CRK platform of products, Oriental Motor integrated a powerful controller to meet this demand while improving upon common microstepping performance offerings in the market by utilizing our 5-phase, new pentagon technology.

The benefits of the CRK Series with built in controller are:

5-phase motors:
• Lower Vibration
• Increased positional accuracy
• Higher resolution
• Wide motor variations for many different applications

Built in controller:
• 3 Operation Modes for control
• RS-485 Communications
• Multiple motion profile options available
• Compact and space savings
• No additional software to buy

The CRK Series product line consists of a compact high performance microstepping driver with up to a maximum step divide of 250 per step, all the advantages of 5-phase performance with Oriental Motor’s proprietary Smooth Drive technology built in. 24 VDC input Unit packages offer an industry leading selection of motor sizes and performance characteristics to meet a wide variety of application demands.

CRK Series with Built in Controller Features and Benefits Motor options:

• High-Resolution type with a basic step angle of 0.36 degree and a stop position accuracy of 2 Arc Minutes (0.034 degree) with no load.
• High-Torque type with 1.3 ~ 1.5 times more torque than compared to our standard 5-phase motor.
• Standard type which offers a good balance of torque and low vibration.
• Tapered Hob geared type effective for inertia reduction, increased torque and resolution with a backlash of 10-60 arc minutes (0.167~1 degree) depending on gear ratio.

3 Driver Operation Modes:
The ability to start or modify stored motion programs through 3 specific operating modes was designed to meet the demands of many different types of applications and industry requirements providing for maximum design and motion control flexibility.

• Direct command entry from terminal, PLC or Master controller. With this method, any command received by the driver sent from a computer, PLC or other master controller will be executed immediately.
• Stand alone operation of running stored programs selected via I/O. With this method, programs that have been previously written and stored in the driver’s memory can be executed by turning on the appropriate combination of inputs and then turning on a START input.
• Running of stored sequences while passing data into the sequences as needed from a computer, PLC or other master controller. With this method, any settable parameter or variable values entered/changed via direct entry from a computer, PLC or other master controller will be utilized when a stored sequence is run.

RS-485 Communications:
By incorporating this robust and cost effective communication method, the CRK Series with built in controller can easily be used with existing PLC or PC master controls in a network or as a stand alone unit without the need for expensive cables or proprietary networks.

• Ability to multidrop up to 16 units.
  *Note: The termination resistor switch on the last unit in line needs to be turned to the on position to ensure proper communication.
• Accepts PLC or PC based programming (ASCII commands), no need for dedicated software.
• Provides warning, alarm or error detection

Multiple Motion Profile examples

• Repetitive positioning
• Stopping via Sensor Input
• Continues operation at variable speeds
• Linked motion, up to 4 moves maximum
• Mechanical or electrical return to home
• PLS-OUT function – Can drive a second driver (driver only, no controller need in second unit) with the same pulse count as the first motor

Space Saving
The driver has a compact size of 1.37in (35mm) width x 3.97in (100mm) length x 2.75in (70mm) depth which helps contribute to a space-saving controller box and device set up.
The drive is made for direct DIN rail mounting, screws are not necessary.

I’m trying to decide between a 5-phase step motor system and a 2-phase step motor system. Can you tell me the differences?

A: In a motor application where noise or vibration is a concern, a 5-phase step motor system would be ideal especially at low speeds.
