FUNCTION These are frequency set points for use with
the following modes:
Inch 1 (M-FR1)
Inch 2 (M-FR2)
Multispeed (M-FR1 to M-FR7)
Crane control (M-FR1 to M-FR4)
The frequency set points may have negative
values thus permitting reverse motor direction
to be selected.
SETTING UP Leave the multi-speed frequencies set to zero
unless required.
Set each multi-speed setpoint to your desired
value. Leave unused multi-speed frequencies
set at zero in case these are inadvertently
selected.
Configure the multi-function input mode
(Screen 66) as necessary to use these inputs.
Refer to Screen 66 for an example of set-up.
39, 40, 41 SECOND ACCELERATION
AND DECELERATION
Screen 39 ACC2=10.0Hz/s
Description ALTERNATIVE ACCELERATION RATE
Min/Max 0.02/500
Units HERTZ/SEC
Screen 40 DEC2=10.0Hz/s
Description ALTERNATIVE DECELERATION RATE
Min/Max 0.02/500
Units HERTZ/SEC
Screen 41 BRK FR= 0.0Hz
Description BREAK FREQUENCY FOR ACCEL/DECEL
Min/Max 0.0/200
Units HERTZ
FUNCTION To provide the option of having two acceleration
and deceleration rates which can be
programmed to change over at a specified
break frequency.
The normal acceleration rate (ACC1 on Screen
15) and deceleration rate (DEC1 on Screen 16)
are active above the break frequency. The
alternative acceleration rate and deceleration
rate are active below the break frequency.
The break frequency is normally set to zero,
thus effectively disabling the alternative rates.
SETTING UP If alternative accelerations are not required,
leave the break frequency at 0.0Hz.
Set the alternative acceleration and
deceleration as desired. Set the breakpoint to
the point above which normal acceleration/
deceleration are required to be active, and
below which alternative rates are required.
The alternative acceleration and deceleration
rates may also be selected by using a multi-
function input (refer Screen 66).
Being realistic with these settings generally
leads to a more successful commissioning.
Where fast accelerations/decelerations are
called for, it is often best to use slower
settings initially, until all other operations are
proven.
