• This can also be used as a general-purpose D/A converter. In this
case, set both the linear accel/decel time constant and the filter time
constant to “0”.
Detailed Description
The order of operations in the speed control mode is shown below.
Due to the bus connection with the servo amplifier, parameters related to
the servo amplifer which have been set as conventional fixed parameters
on the controller side (such as controller pulse, rated speed, number of
feedback pulses per rotation, etc.) are automatically read from the servo
amplifier at power ON.
Therefore, the following parameters do not exist among MP940 fixed
motion parameters.
• Encoder Selection
• Rotation Direction During Absolute Encoder Use
• Rated Speed
• Number of Feedback Pulses Per Rotation
• Maximum Number of Absolute Encoder Rotations
The following parameters are fixed in the MP940:
• Pulse Counting Mode Selection: A/B format, fixed at quadrature
