Associating a fault with a latched, custom-configured output does not latch the fault itself. After the cause of a non- latched fault is corrected, the drive re-enables without operator intervention.

  • Page 15: Commutation Modes

    Accelnet & Stepnet Plus Panels User Guide 16-01339 Rev 07 Using EtherCAT, the distributed clock feature can be used to establish PWM switching frequency synchronization among the network connected drives. Typically one drive acts as the Sync 0 message producer. The master then adjusts the Sync 0 frequency and phase in the slaves to so that they are all in-sync.
  • Page 16: Operating Modes

    OOPS AND ODES Copley Controls Accelnet & Stepnet Plus Panel servo drives use up to three nested control loops, current, velocity, and position, to control a motor in three associated operating modes. Plus Panel stepper drives typically operate in microstepping mode which is a form of open-loop position and velocity control. When stepper motors are equipped with encoders, they can operate stepper motors as brushless servo motors that use the same nested control loops as the servo drives.
  • Page 17 Accelnet & Stepnet Plus Panels User Guide 16-01339 Rev 07 ASIC TTRIBUTES OF ONTROL OOPS Control loops (and servo control loops in general) share several common attributes: Loop Attribute Description Every loop is given a value to which it will attempt to control. For example, the velocity Command input loop receives a velocity command that is the desired motor speed.
  • Page 18: Current Loop Inputs

    Accelnet & Stepnet Plus Panels User Guide 16-01339 Rev 07 URRENT ODE AND URRENT URRENT IAGRAM As shown below, the “front end” of the current loop has filters and a limiting stage. The limiting stage accepts a current command, applies limits, and passes a limited current command to the summing junction. The summing junction subtracts the actual current (represented by the feedback signal) from the limited current and produces an error signal.

The primary effect of this Cp - Current loop proportional gain is to increase bandwidth (or decrease the step-response time) as the gain is increased.

    Accelnet & Stepnet Plus Panels User Guide 16-01339 Rev 07 OSITION ODE AND OSITION OSITION IAGRAM The drive receives position commands from the digital or analog command inputs, over the CAN interface or serial bus, or from the CVM Control Program. When using digital or analog inputs, the drive's internal trajectory generator calculates a trapezoidal motion profile based on trajectory limit parameters.
  • Page 23 Accelnet & Stepnet Plus Panels User Guide 16-01339 Rev 07 RAJECTORY IMITS In position mode, the trajectory generator applies the following user-set limits to generate the motion profile. Limiter Description Maximum Velocity Limits the maximum velocity of the profile. Maximum Acceleration Limits the maximum acceleration rate of the profile.
  • Page 24: Input Command Types

    Accelnet & Stepnet Plus Panels User Guide 16-01339 Rev 07 OSITION The position wrap feature causes the position reported by the drive to “wrap” back to zero at a user-defined value instead of continually increasing. Once set, the reported position will be between 0 and n-1 where n is the user entered wrap value.

The Measure function takes 10 readings of the analog input voltage over a period of approximately 200 ms, averages the readings, and then displays the results.
  • Page 26 Accelnet & Stepnet Plus Panels User Guide 16-01339 Rev 07 PWM I NPUT OMMANDS ORMATS The drive can accept a pulse width modulated signal (PWM) signal to provide a current command in current mode and a velocity command in velocity mode. The PWM input can be programmed for two formats: 50% duty cycle (one-wire) and 100% duty cycle (two-wire).
  • Page 27 Accelnet & Stepnet Plus Panels User Guide 16-01339 Rev 07 IGITAL NPUT OMMANDS HREE ORMATS In position mode, the drive can accept position commands via two digital inputs, using one of these signal formats: pulse and direction, count up/count down, and quadrature. In all three formats, the drive can be configured to invert the command.

    Description RS-232 port The RS-232 port is a three-wire, DTE, full-duplex port. Control commands can be sent over the RS-232 port using Copley Controls ASCII interface commands. In addition, CME software communicates with the drive (using a binary protocol) over this link for drive commissioning, adjustments, and diagnostics.

  • Page 35: Brake Operation

    Accelnet & Stepnet Plus Panels User Guide 16-01339 Rev 07 RAKE PERATION RAKE UTPUTS Many control systems employ a brake to hold an axis when the drive is disabled. Accelnet & Stepnet Plus Panel drives have digital outputs designed specifically for brake control. Unlike the other outputs, these brake outputs have internal fly-back diodes connected to +24 Vdc input.
  • Page 36 Accelnet & Stepnet Plus Panels User Guide 16-01339 Rev 07 OTOR IRING ETECTION When a brake is in use, the drive can check for a disconnected motor. Upon enable, the drive will apply current to the motor output while keeping the brake engaged for the Brake Hold Time on Enable. If no current can be detected in the windings, the brake will not be released and a Wiring Detection Fault will occur.

    Accelnet & Stepnet Plus Panels User Guide 16-01339 Rev 07 ROTECTION (STO) ORQUE All of the Accelnet & Stepnet Plus Panels models provide a Safe Torque Off (STO) function. Two opto-couplers are provided which, when de-energized, prevent the upper and lower devices in the PWM outputs from being operated by the digital control core.

The drive’s position loop uses complementary methods for handling position errors: following error fault, following error warning, and a position-tracking window.
  • Page 40 Accelnet & Stepnet Plus Panels User Guide 16-01339 Rev 07 RIVE ESPONSE TO A ATCHED OLLOWING RROR AULT When a latched following error fault occurs, the drive disables the output PWM stage without first attempting to apply a deceleration rate. If a motor brake is in use, the brake output will turn off immediately, engaging the motor brake.

  • Page 105 Accelnet & Stepnet Plus Panels User Guide 16-01339 Rev 07 SSI A BSOLUTE NCODER The SSI (Synchronous Serial Interface) is an interface used to connect an absolute position encoder to a motion controller or control system. The drive provides a train of clock signals in differential format to the encoder which initiates the transmission of the position data on the subsequent clock pulses.
  • Page 106 Accelnet & Stepnet Plus Panels User Guide 16-01339 Rev 07 BSOLUTE NCODER The EnDat interface is a Heidenhain interface that is similar to SSI in the use of clock and data signals, but which also supports analog sin/cos channels from the same encoder. The number of position data bits is programmable as is the use of sin/cos channels.
