8. Quick tuning
1. After a complete check of wiring, turn the power on:
• The following voltages must be present:
Terminal 7, +10V to terminal 9 (on regulation board)
Terminal 8, -10V to terminal 9 (on regulation board)
Terminal 19, +24…30V to terminal 18 (on regulation
board)
• Check DC link voltage by pressing [Down arrow] to
get “Monitor”, then [Enter], then [Down arrow]
to“measurements”, then [Enter], then [Down arrow]
to “DC link voltage”, then [Enter].
The value should be:
275-357 VDC for 230 VAC input
480-650 VDC for 400 VAC input
550-715 VDC for 460 VAC input
If the DC Bus is not within these limits, check the AC
line voltage.
2. Default to Factory Values: If you are not certain of the
drive configuration, it will be necessary to default to factory
values or copy in a file from a PC. It is important to be
certain you are starting from a known configuration. To
default to factory values:
• Default to working memory: Push [Left arrow] to
get back to “Monitor”, then [Down arrow] to “Spec
Functions” and then [Enter]. Push [Down arrow] to
“Load Default” and [Enter]. The factory values will
now be loaded into the working memory, the original
values are still in permanent memory.
Note:
Step 2 can be skipped if you know that the drive is loaded
with factory defaults (as it comes out of the shipping
carton).
3. Set Line Voltage:
• Press [Left arrow] to “Spec functions” then [Up
arrow] to “BASIC MENU”, then [Enter], then [Down
arrow] to “Drive type”, then [Enter] to “Mains voltage”
and [Enter]. Now using the [Up arrow] / [Down
arrow] keys, change the voltage to your nominal AC
input rating. Then [Enter] to set the value.
4. Adaption to maximum ambient temperature:
• Press [Down arrow] to “Ambient temp” then [Enter].
Now using the [Up arrow] / [Down arrow] keys, set
the maximum ambient temperature value: 40°C or
50°C, then [Enter].
5. Load Default Motor Values:
• Press [Left arrow] until you are back to “BASIC MENU”
and then [Down arrow] to Drive Parameter, then
[Enter], then [Down arrow] to Motor Parameter,
[Enter], then [Down arrow] to “Load Motor Par” and
[Enter]. Use the [Up arrow]/[Down arrow] keys until
the display is the correct motor voltage, then [Enter].
For 460 VAC motors, select 460, and for 380/400 VAC
motors select 400.
6. Set Actual Motor Data:
• Press [Left arrow] until back to “Drive parameter”,
then [Enter] to get “Mot plate data” and [Enter] to
“Nominal Voltage” then [Enter] again to see the value.
Using the [Up arrow]/[Down arrow] keys to change
the value and the [Left arrow] to move the character
position. When correct press [Enter].
• Press [Down arrow] to “Nominal speed”, [Enter], then
use the [Up arrow] / [Down arrow] keys to get the
nominal speed on the motor nameplate. Press [Enter]
to set data. Note, some manufacturers of vector
motors put the synchronous speed (600, 900, 1500,
1800, 3600 RPM), rather than the slip speed at 60 Hz
on the nameplate. If this is done, you MUST estimate
slip speed. Figure 20 rpm less than the synchronous
speed for these cases.
• Press [Down arrow] to “Nom frequency” and [Enter]
and set to the nominal frequency on the nameplate
(50 or 60 Hz) Press [Enter] to set data.
• Press [Down arrow] to “Nominal current” and [Enter]
and set to the nominal current on the nameplate (rated
current) by using the [Up arrow] / [Down arrow] keys.
Press [Enter] to set data.
If the drive will “not accept” the value entered, the
most common cause is trying to [Enter] a value for
“Nominal Current” that is less than 30% of the drive
rating. This is not allowed due to parameter problems
encountered with a small motor and a large drive. Go
back to step 6 and repeat the entries. If this doesn’t
work, see the Overflow List in the troubleshooting
section of this book.
• Press [Down arrow] to “Cos phi” and [Enter] and set
the nominal power factor on the nameplate by using
the [Up arrow] / [Down arrow] keys (accept the
default if you don’t know). Press [Enter] to set data.
Press [Down arrow] to “Base Voltage” and [Enter]
and set the base voltage by using the [Up arrow] /
[Down arrow] keys (usually rated voltage). Press
[Enter] to set data. Look in the manual for both Base
Voltage and Base Frequency when operating the motor
above normal synchronous speed.
• Press [Down arrow] to “Base Frequency” and [Enter],
set to the base frequency by using the [Up arrow] /
[Down arrow] keys (usually rated frequency). Press
[Enter] to set data.
• Press [Down arrow] to “Take motor par” and [Enter]
and set all the motor parameters. If, when you do
this, a message saying “Over-range error XXX”
appears, there is something wrong with the data
you have entered. The drive has NOT ACCEPTED
the values you have entered. The most common cause
