3 WIRING CONNECTIONS
• Wire up the panel/drive/motor in accordance with the instructions in the operator's manual and applicable safety regulations. In case of any doubts, contact our After-Sales Service.
• Check the correct dimensioning of the drive/motor. Compare the rated voltages and currents.
• Make sure the maximum power voltage to terminals L1, L2, L3 does not exceed the specifications (see
EN60204-1, section 4.3.1) to avoid damaging the drive.
• Make sure the system is properly earthed.
• The user is responsible for the cutout fuses on the AC or DC supply of the converter.
• Be careful of the cable cross sections; refer to the "connections" table and ensure conformity with IEC227-2.
• The cables connected to the drive by means of the terminal board should not be strengthened by soldering
Sn-Pb (EN60065, art.15.3.5).
• DO NOT
remove the power connections from the drive when this is energised.
• After interrupting the power supply and after the converter has been switched off, allow at least 5 minutes to pass before disconnecting the motor leads from the drive, as hazardous voltages could persist.
• DO NOT
open the converter. This could be hazardous and immediately invalidate the warranty.
3.1 Protection devices
The drive can be connected to an A.C. mains having at most 5kA of short-circuit current and maximum voltage of 480V. The drive is without integrated overload protection. Table for dimensioning the fuses:

The 24 V powers the drive electronics and therefore controls drive switch on and off.

5 CONNECTION TO POWER MAINS

Two modes that can be selected with Pr39.0:
- programme 0 for three-phase mains supply 180V~ MIN to 528V~ MAX or single-phase at 305V~ MAX.
- programme 1 for D.C. supply - 254V= MIN to 744V= MAX. Enter value in Pr21, save, switch off and then
back on. Æ A third possibility exists - low-voltage supply (see Operator's Manual).
With both the D.C. and the A.C. supply, the undervoltage threshold is set not below 70% of VMIN (254V= or
180V~). If the bit b39.8 is set at one, upon the return of the mains voltage, the undervoltage alarm is automatically reset.

(*) these signals cannot be used as feedback on the position loop, but can be used as encoder input counters.
(**) when the resolver is connected to X6, do not connect the Less Wiring encoder and the incremental encoder to X7.
To the connector, a variable supply is available with voltage that can be set at 5, 8 or 12V=, by means of a parametric switch. In the case of 5 and 8 V voltages, these can be regulated with a feedback by means of a sensing pair to offset any voltage drops of the cables. In the case of 12V, the feedback is internal and any voltage drop cannot be offset. Bit Pb64.0 indicates whether the sensing function is on, otherwise the voltage set in open loop is regulated. To the in encoder connector, a fixed isolated voltage of 5V is available.

10 FIRST CONVERTER START-UP
The drive is supplied from the factory with default programming. Remember that the Hi-drive can control brushless synchronous or asynchronous motors. Before entering the
motor data, programme Pr31: write “0” for brushless motor (default condition), “1” for asynchronous motor.
At this point the mechanism must be set with the fundamental parameters to characterise the connected motor (motor plate data). The fundamental parameters are:
Pr29 Number of motor poles N Pr32 nominal motor speed r.p.m. Pr33 rated motor current (eg. 2.5A, write 2.5) A Pr46 motor phase-phase resistance (eg. 1.8Ω, write 1.8) ohm Pr47 motor phase-phase inductance (eg. 2.6mH, write 2.6) mH Pr60 number of resolver poles N
In the case of an asynchronous motor, the previous data must be completed with the following parameters:
Pr45 basic speed r.p.m. Pr48 sliding r.p.m. Pr49 magnetisation current A
synchronous motor
Pr32 limit speed of motor r.p.m.
After setting the parameters for motor characterisation, the operator must give the data saving command,
Pb42.15 (with drive disabled) and start the mechanism again. The drive will calculate the correct values of Pr2,
Pr3, Pr16, Pr17, Pr18 and Pr19. The gain calculation is done if the drive is in default condition.
To change the entered parameters, put bit Pb42.1=1. The drive, at this point, again asks for the default
parameters (alarm 15). After data entering, save and start the drive again. The parameters Pr2, Pr3, Pr16, Pr17, Pr18 and Pr19 will be recalculated according to the entered values.
10.1

First Hi-drive start-up

Below, the steps are shown to be carefully followed during first converter start-up.
1) Connect the motor to the converter, carefully following the manual diagrams.
2) Make sure the converter is disabled.
3) Start the converter.
4) Make sure no alarm has tripped.
5) Set the analogue reference at 0 V (pin 13, 14 of terminal board X5), and enable the converter (24V at the
pin that enables the drive).
6) Now the motor shaft must be stopped; when the analogue reference voltage changes, the motor speed
must change proportionately. If it does not, check the wiring harness. The converter is made with default values already set.
10.2

Setting the default parameters

To set the default parameters (which change all previously set parameters) proceed as follows:
- start the converter
- disable the converter by means of software command (Pb40.9=0) or via hardware (before starting the
converter)
- set Pb39.13=0
- give the command Pb42.12=1, which enables drive default parameter loading
- enter the fundamental parameters (motor plate data, see para. 3.2)
- save the setting with commands Pb42.14 e Pb42.15 (the drive must be disabled)
- stop and start the drive again.
11 USE OF KEYBOARD (OPTIONAL)
S, SHIFT, is used in combination with the other keys to enable the cursor to move inside the fields:
o Together with key T, movement inside the fields is made in the opposite direction (anticlockwise). o Together with key + o – to move the cursor inside the field on a figure with greater or less "weight".
+, increases the datum shown by the cursor; if PLC instructions. –, decreases the datum shown by the cursor; if PLC instructions. T, the purpose of this key is to change the field shown by the cursor. E, ENTER, confirms datum entering or change. The changed or entered datum or instruction must be saved
before changing the display page, otherwise the change made will be lost. IMPORTANT: the instructions can also be changed when the Pico-PLC is running (Pr39.13=1), and so before changing anything, it is best to stop the Pico-PLC.

-If the alarm persists, disable the drive, interrupt power to the motor, disconnect the power supply to the drive (24VDC). Disconnect the PTC connector from the drive, and make a connection short-circuiting the PTC (between PTC+ and PTC-) on the terminal board of the drive itself. Power the drive (24VDC). If the alarm continues, the drive is faulty, otherwise the PTC on board the motor is faulty (after completing the test, remove the connection short-circuiting the PTC) Check the cooling fans and any blockages/restrictions in air flow. Check the braking cycle. Check the room temperature of the switchboard where the drive is fitted and outside room temperature.
The drive power voltage is below minimum threshold: voltage too low.
Check the cooling fans and any blockages/restrictions in air flow.
Check the room temperature of the switchboard where the drive is fitted and outside room temperature. Braking resistance in short circuit. If an external braking resistance is connected to the drive, check its condition and wiring harness. Check the FBK speed settings. Check the FBK speed connection.
Check the settings of the position FBK. Check the connection of the position FBK.
Check the connections of the position loop and the connectors on both sides (drive-motor). The drives goes in I²T due to an overload (more power is required than that being supplied). Check:
-The wiring between the drive and the motor (there must be no switched-over phases). Above all mind the motors with terminal board rather than connector: it is easy to make a mistake. Make sure you keep to the wiring diagrams.
