Table 7-26: Setting of parameter CS (Selection of acceleration profiling pattern)
CS setting Pattern Feature
CS1
Constant
acceleration
· Accelerating rate is constant.
· The maximum acceleration is the lowest among them,
however vibration is higher.
CS2 Modified sine
· Suites for high velocity and heavy load operation.
· The maximum factor of (V × a) is low.
CS3 Modified trapezoid
· Suites for high velocity and light load operation.
· The maximum acceleration is lower.
CS4 Cychloid
· Suites for high velocity and light load operation.
· Low vibration.
CS5 Half sine
· Suites for high velocity and light load operation.
· The maximum velocity is low, however vibration is higher.
l The acceleration profiling is applicable for the positioning commands of AR, AD, IR, and ID. It
can be programmed only to the channels of CH0 to CH31 for the Programmable Indexer
operation. You may set the conventional constant acceleration on the channels CH32 to CH63.
l Acceleration of the acceleration profiling will be a mean acceleration set by parameter MA
(CA).

à In default of the part of deceleration setting following the comma (,) of parameters CS
or MA, the settings on deceleration follow those of acceleration.
à Execution of AR, AD, IR, or ID command starts a Programmable Indexer or an
RS-232C operation with the acceleration profiling set by the above procedures.
