It can operate on a distributed control network, as a stand-alone indexing drive, or with external motion controllers. Two versions are available to support digital quadrature, or analog sin/cos encoders. Indexing mode enables simplified operation with PLC’s which use outputs to select and launch indexes and inputs to read back drive status. Additionally, a PLC can send ASCII data that can change motion profiles so that one index can perform various motions as machine requirements change. The CANopen distributed control architecture is also supported. As a CAN node operating under the CANopen protocol, it supports Profile Position, Profile Velocity, Profile Torque, Interpolated Position, and Homing. Up to 127 drives can operate on a single CAN bus and groups of drives can be linked via the CAN so that they execute motion profiles together. Operation with external motion controllers is possible in torque (current), velocity, and position modes. Input command signals can be ±10V (torque, velocity, position), PWM/Polarity (torque, velocity), or stepper format (CU/CD or Step/Direction).

Accelnet R21 RUGGEDIZED DIGITAL SERVO DRIVE FOR BRUSHLESS/BRUSH MOTORS R21 RoHS CME 2™ SOFTWARE CANOPEN NETWORKING Amplifier setup is fast and easy using CME 2™ software which communicates with the amplifier over CAN or an RS-232 link. All of the operations needed to configure the amplifier are accessible through this powerful and intuitive program. Auto-phasing of brushless motor Hall sensors and phase wires eliminates “wire and try”. Connections are made once and CME 2™ does the rest thereafter. Encoder wire swapping to establish the direction of positive motion is eliminated. Based on...

The command inputs take digital and analog signals in a variety of formats: Pulse/Direction Inputs PWM/DIRECTION INPUTS Duty = 0~100% [IN7] [IN8] Current or Velocity Mode ±10V Analog...

Accelnet R21 R21 RUGGEDIZED DIGITAL SERVO DRIVE FOR BRUSHLESS/BRUSH MOTORS RoHS DIGITAL INPUTS has nine digital inputs, eight of which have programmable functions. Input [IN1] is not programmable and is dedicated to the drive Enable function. This is done to prevent accidental programming of the input in such a way that the controller could not shut it down. Two types of RC filters are used: GP (general purpose) and HS (high speed). Input functions such as Step/Direction, CU/CD, Quad A/B are wired to inputs having the HS filters, and inputs with the GP filters are used for general purpose...
