Range Description
ACC. TIME
10 SEC.
1-30sec.
Note:
The range of the
ACC. TIME can
be extended to
1-90 sec. by
using the
EXTENDED
SETTING as
described in
section
6.4.4
page 42.
Sets ACCELERATION TIME of the motor.
Determines the motor’s voltage ramp-up time, from initial to
full voltage.
It is recommended to set ACCELERATION TIME to the
minimum acceptable value (approx. 5 sec).
Notes:
Since CURRENT LIMIT overrides ACC. TIME, when
CURRENT LIMIT is set low, the starting time will be longer
than the ACC. TIME setting.
When the motor reaches full speed before voltage reaches
nominal, ACC. TIME setting is overridden, causing voltage
to quickly ramp-up to nominal.
Using starting curves 2, 3, 4 prevents quick ramp up.
MAX. START TIME
30 SEC.
1-30sec.
Note:
The range of the
MAX. START
TIME can be
extended to
1-250 sec. by
using the
EXTENDED
SETTING as
described in
section
6.4.4
page 42.
Sets MAXIMUM START TIME.
The maximum allowable start time, from the start signal to the
end of the acceleration process. If voltage/speed does not
reach nominal during MAX. START TIME then HRVS-DN will
trip the motor and create a fault. The LCD will display the
LONG START TIME fault message.
For example, this can occur when the CURRENT LIMIT
setting is too low.
NUMBER OF STARTS
1
1-10/ OFF Sets NUMBER OF STARTS permitted during STARTS
PERIOD.
Limits the number of starts during the period of time defined
by STARTS PERIOD.
If you try to start even one more time within that period the
START INHIBIT period will take effect.
STARTS PERIOD
20 MIN.
1–60min. Sets STARTS PERIOD during which NUMBER OF STARTS
is being counted.
START INHIBIT
15 MIN
1–60min. Sets START INHIBIT time which starting is disabled after TOO
MANY STARTS trip.
During the START INHIBIT period the WAIT BEFORE RST
XX MIN message will be displayed.
