S-Pattern Acceleration/Deceleration; Analog Output - Mitsubishi Electric Melservo-J2-SUPER series Instruction Manual

5. PARAMETERS

5.2.3 S-pattern acceleration/deceleration

In servo operation, linear acceleration/deceleration is usually made. By setting the S-pattern
acceleration/deceleration time constant (parameter No.14), a smooth start/stop can be made. When the S-
pattern time constant is set, smooth positioning is executed as shown below. When the S-pattern
acceleration/deceleration time constant is set, the time from a start to the output of Movement complete
(PED) increases by the S-pattern acceleration/deceleration time constant.

5.2.4 Analog output

The servo status can be output to two channels in terms of voltage. Use this function when using an
ammeter to monitor the servo status or synchronizing the torque/speed with the other servo.
