156 Epsilon EP-P Drive Reference Manual
www.controltechniques.com Revision: A4
Drive Output Name
DriveOutput.#.Name
This is a text string up to 12 characters that can be assigned to a given output. It allows the user to use application specific terminology in
naming digital outputs.
Drive Output State
DriveOutput.#State
This destination sets the current state of an output line.
Drive Output Encoder Scaling
DriveOutputEncoder.Scaling
This parameter allows scaling of the drive encoder output resolution in increments of one line per revolution. Allowable range is from one line
per revolution up to the actual density of the encoder in the motor. If the Encoder output scaling is set greater than the motor encoder density
the output scaling will be equal to the motor encoder density.
Drive Output Encoder Scaling Enable
DriveOutputEncoder.ScalingEnable
When on, this parameter enables the use of the drive encoder output scaling feature.
Drive Serial Number
DriveSerialNumber
This displays the serial number of the Drive.
Dual Loop Enable
DualLoopEnable
This Destination is used to initiate, turns on, the Dual Loop feature. The system will remain in this mode as long as this Destination is active.
DualLoopEnable can be assigned or initiate by a user program.
Dual Loop Encoder Ratio - Motor Encoder
DualLoopMotorEncoder
This parameter is the numerator in the ratio used to define the mechanical ratio between the Motor Encoder and the Position Feedback
Encoder. This parameter is only used when Dual Loop Control Mode is enabled, and must be set correctly to achieve the correct target
velocity.
Motor - Position Feedback
DualLoopMotorPosnFdbk
This is the actual motor position in user units. The difference between the PosnCommand and the PosnFeedback is the FollowingError.
Motor - Velocity Feedback
DualLoopMotorVelFdbk
This is the feedback (or actual) velocity. It is calculated using the change in position of the motor encoder. It will always return the actual motor
velocity - even in synchronized applications in which the master axis is halted during a move.
Dual Loop Encoder Ratio - Position Encoder
DualLoopPositionEncoder
This value along with the Motor Encoder value define the mechanical ratio of motor turns to position encoder turns. Typically these values will
have units of encoder counts since this will give the highest degree of accuracy. The user must calculate the mechanical ratio as accurately as
possible for best results.
Dual Loop Position Feedback Polarity
DualLoopPosnFdbkPolarity
Position Feedback Polarity defines the direction of the position encoder that corresponds to a positive position change. This value is somewhat
arbitrary, since the position encoder can be mounted to spin CW or CCW as the material moves "forward". If this value is not set correctly in
Dual Loop mode the motor will rotate in the opposite direction as desired.
