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 when the positioning starts until the
movement finish (MEND) is output will increase by the time equivalent to the S-pattern time constant
setting.

5.2.4 Analog output
The servo status can be output to two channels in terms of voltage. The servo status can be monitored
using an ammeter.
