HPDxxN – High Power User’s Manual
24
In addition to the parameter values and the pico-PLC instructions, the display may show the
following messages:
r. xx
At the time of power-up this message indicates the software version installed (2 seconds
approx.).
IdLE
At power-up and in correspondence with Pr0 this message shows that no alarms are
present and the system is disabled.
run
At the time of power-up and in correspondence with Pr0 this message indicates that no
alarms are present and the drive is enabled; the motor shaft may be spinning.
Er. xx
In correspondence with Pr0 this message indicates that the drive has detected an alarm (xx
indicates the alarm code) and has therefore been disabled. When an alarm is detected the
display automatically switches to parameter Pr0 and shows the alarm code.
dcbuS
In correspondence with Pr0 this message indicates that the drive is not operating at low
voltage (b40.10=0) and that DC bus voltage is still below the 120 V threshold; the inrush
current circuit is still connected so the drive is not yet ready (b41.4=0).
Prxx
Indication of parameter xx (value displayed by pressing “M”).
Pb. xx
Indication of bit parameter xx.
bxx.yy
Indication of bit yy of parameter xx; press “M” to display bit status.
In. xx
Indication of instruction xx of PLC program.
donE
Displayed for approximately 1 second each time a command is entered.
rESet
Displayed for approximately 1 second each time an alarm reset command is entered
(b99.10).
tESt
Displayed during wiring test (b70.3).
rEtrY
It’s displayed when a writing error is detected storing the pico-PLC instructions (b99.14)
or while saving parameters (b99.15).
3.2 Commissioning the HPD N drive
The steps described in this section must be followed carefully when the drive is started up for the
first time.
1)
Connect the motor to the drive in compliance with the wiring diagrams in the manual.
2)
Make sure the drive is disabled (terminal 11 of board X3 must be open)
3)
Power up the drive.
4)
After some seconds the display shows “IdLE”.
5)
Setting essential parameters:
Pr33 calculation (rated current)
where:
InM is rated motor current at zero rpm in Ampere
InD is rated drive current in Ampere
The maximum value of
Pr33
is
50.0
for the HPD25N and
67.0
for
HPD35N, 45N, 67N
Pr19 calculation (peak current)
Pr33 =
InM
InD 2
