The ramp rate parameters (
Acceleration Rate 1
(02.011) to
Acceleration Rate 8
(02.018),
Jog Acceleration Rate
(02.019),
Deceleration Rate 1
(02.021) to
Deceleration Rate 8
(02.028) and
Jog Deceleration Rate
(02.029)) are specified in s / Ramp rate frequency for Open-loop mode and s /
Ramp rate speed for RFC-A and RFC-S modes. Ramp rate frequency and Ramp rate speed are selected with
Ramp Rate Units
(02.039) as defined in
the table below.

Maximum frequency and Maximum speed are defined by

(11.045) = 0,
or
M2 Maximum Reference Clamp
(21.001) if
Select Motor 2 Parameters

If
S Ramp Set-up Mode
(02.041) = 1 the percentage of the ramp to Maximum frequency or Maximum speed that includes half the S ramp profile can be
specified with
S Ramp Percentage
(02.040) as shown in the diagram below. If motor map one is active (i.e.
Select Motor 2 Parameters
(11.045) = 0),
the acceleration or deceleration times are defined by
Acceleration Rate 1
(02.011) and
Deceleration Rate 1
(02.021) respectively irrespective of which
ramps rates are selected. The maximum maximum frequency/speed is defined by
Maximum Reference Clamp
(01.006). The time for the
frequency/speed change remains constant at the time defined by the acceleration of deceleration rate, and so as the percentage S ramp is changed the
maximum acceleration is modified automatically. If motor map 2 is selected then
M2 Maximum Reference Clamp
(21.001),
M2 Acceleration Rate 1
(21.004) and
M2 Deceleration Rate 1
(21.005) are used to define the ramp profile.
