7. FIRST STARTUP
For the signal wiring and power wiring, please refer to the Sinus Penta’s Installation Guide.
Parameter programming is detailed in the START-UP MENU.
7.1. “IFD” Control Algorithm
SINUS PENTA drives are factory set with the IFD (C010) control algorithm for the first startup of the equipment. The
default functions of the drive terminals are given in the table below. For more details, please refer to the Sinus Penta’s
Installation Guide.
1) Wiring:
Follow the instructions stated in the “Caution Statements” and “Installation” sections
(Installation Guide).
2) Power on:
Power on the drive and do not close the link to the ENABLE-A and ENABLE-B
inputs to prevent the motor from running. Check if the display/keypad turns on.
3) Parameter setting:
The equipment startup is made easier by the START-UP MENU, which is a wizard
for the set-up of the main motor control parameters.
From the START-UP MENU, set the following:
1. The real power supply voltage in C008
. It is possible to select the rated
mains voltage range or the power supply from a DC-
bus stabilized by a
Regenerative Penta;
2. The motor ratings by way of:
• C015 (fmot1) rated frequency
• C016 (rpmnom1) rated rpm
• C017 (Pmot1) rated power
• C018 (Imot1) rated current
• C019 (Vmot1) rated voltage
• C029 (Speedmax1) max. allowable speed.
The motor V/f pattern may be programmed in C013. For loads with quadratic torque
in respect to the rpm (centrifugal pumps, fans, etc.), set C034 (preboost1) to 0%.
4) Autotune (motor
stopped):
In case of IFD motor control when slip compensation is inactive (C039=0%) no
autotune is required. On the other hand, when slip compensation is active, it is
recommended to compute stator resistance C022.
The steps to take to perform motor autotune are the following:
With the ENABLE-A and ENABLE-B commands open, access the AUTOTUNE
MENU
and set I073 = [1: Motor Tune] and I074
= [0: All Ctrl no rotation]. Use the
ESC key to accept changes.
Close the ENABLE-A and ENABLE-B
commands and wait until tune is complete
(Warning “W32
Open Enable” is displayed). The drive has computed and saved the
values for C022 (stator resistance).
If alarm “A097 Motor Wires KO” trips, check the motor wiring. If alarm “A065
Autotune KO” trips, this means that the ENABLE
command has opened before
autotune was complete. In this case, reset the drive by
sending a command from
terminal MDI3, or press the RESET
key in the display/keypad and perform the
autotune procedure again.
5) Overload: Set parameters C043, C044 and C045 as the maximum desired overload current.
6) Startup:
Activate the ENABLE-A input (terminal 15), ENABLE-B input (terminal S) and the
START input (terminal 14) and send a speed reference: the RUN LED and REF
LEDs will come on and the motor will start running
. Make sure that the motor is
rotating in the correct direction. If not, set parameter C014 (Phase Rotation) to
[1:Yes], or open the ENABLE-A, ENABLE-B and START
inputs, remove voltage
from the drive and, after waiting at least 20 minutes, swap two of the motor phases.
