PIN numbers range 21 to 35.
A different dow n ramp time is settable for stopping
modes. See 6.5.2 STOP MODE RA MP / Stop ramp
time PIN 56.
A different up/down ramp time is settable for JO G
control. See 6.3.6 JOG CRA WL SLA CK / Jog/Slack
ramp PIN 43.
Summary of available functions.
This block sets the rate of acceleration and
deceleration of the motor independantly of the
incoming reference. There are 4 independent
up/do wn forw ard/reverse ramp times, and an output
indicates that ramping is taking place. The output
can be held, or preset to any value with preset
commands from various sources for a wide number
of applications. The ramp shape can be profiled to a
classic S shape for smooth control. See 6.2.13 RUN
MO DE RA MPS / Ramp S-profile % PIN 32.
See 6.3 CHA NGE PARA METERS / JOG CRA WL
SLA CK and 6.5 CH ANGE PARAMETERS / STOP
MO DE RA MP. These have their o wn ramp rate
times which overide the run mode ramps. The
incoming reference can have a minimum speed
imposed in either direction. The ramp preset
function is momentary in jog mode.
Note that the RUN MO DE RA MP may be
programmed to be active when the unit is in stop
mode. See 6.2.1 RUN MODE RA MPS / Block
diagram including JOG. This function is useful in
cascaded systems.
