When the green RUN button on the outside of the control box is pressed
the motor speed will ramp up to the set speed in 5 sec.
When the red STOP button is pressed the motor speed will ramp down to
zero in 2 sec.
To display the motor speed first go to the main menu by using the
“ESC” key, then press the “
Ʌ ” key until the FOUT led is on. The display
now shows the actual drive output frequency in Hz. To see how it
changes stop the machine and restart it, you will see the speed moving
from zero to the set speed. To display the motor current press the “
Ʌ
”
key again. The “A” behind the value is the unit “Ampere”
3. Changing factory defaults
The following parameter have been changed from their factory default
values. Do not change any of these values before first consulting MLS
Test Systems. Please see section 1, Programming, which explains how to
change a parameter.
1.1 The acceleration time have been decreased from 10 sec. to 5 sec
and the deceleration time from 10 sec. to 2 sec. (Par. C1-01 = 5,
Par. C1-02 = 2)
1.2 Reverse running has been disabled. (Par. b1-04 = 1)
1.3 Remote control has been enabled (Start & Stop buttons) and
remote frequency control (Potentiometer) is enabled (Par. b1-02
= 1, Par b1-01 = 1)
1.4 The frequency at which max output voltage occurs was changed
from 60Hz to 50Hz. (Par. E1-04 = 50, Par. E1-06 = 50, Par E1-
07 = 1.3, Par E1-09 = 1.3)
1.5 The max. frequency have been set to 48 Hz. (Par. d2-01 = 96%)
1.6 Tripping on over torque has been enabled at 160% over 1 sec.
(Par. L6-01 = 4, Par. L6-02 = 160%, Par. L6-03 = 1s).
