Commissioning
140 BA8230
5.3 General With the basic 8230 frequency inverter settings made in the factory the drive is ready
for operation when the mains supply and the motor are connected and the 8230
frequency inverter can be operated using the BDE control unit. The terminal strip is
wired for this method of control, see also section 2.7.2 Terminal wiring - Comments.
The operator must set the basic 8230 frequency inverter parameters for the actual
data required according to section 5.6.2 onwards to match the 8230 frequency
inverter to the mains supply, the motor and the plant.
Commissioning should therefore be effected in 3 stages:
1. Connecting the mains and motor
2. First commissioning using the BDE control unit
The existing mains data, motor data and type of load (squared or constant) are
entered on the menu “06 Type data”. Then the main user parameters such as
minimum and maximum speed, acceleration and braking ramps are to be set.
After checking or adjusting the motor potentiometer parameters the drive is then
commissioned using the control unit.
3. Wiring the terminal strip
When the drive has run and the main drive data is set under section 2, the
terminal strip is wired according to the requirements and the higher level control
used.
This concludes basic commissioning.
5.4 Mains and motor connection Connect the unit to the mains and motor according to section 2.7.1.
First check whether the mains voltage lies within the 8230 frequency inverter rated
voltage tolerances (380 V AC - 480 V AC).
Power and electronics cables must always be laid separately. The installation and
connection instructions in section 3 must be observed.
The connection cables must have the cross-sections stated in section 2. Fuses of
class gL recommended in section 2 must be used to protect the power cables against
overload.
The semiconductor fuses and mains chokes to be used are listed in section 2. The
mains chokes are included in the 8230 frequency inverter scope of supply and are
supplied loose. The mains contactor, RFI filter, power dump and motor filters are
options and are only required if necessary for the connection.
Standard motors or motors with equivalent insulation features can be connected to
8230 frequency inverters, if mains connecting voltage is U
N
ˆ 460 V. The standard
motors 400 V ... 460 V are rated for rates of voltage rises and voltage peaks up to
1300 V. For other types, it may be necessary to ask the motor supplier whether the
motors are suitable for inverter operation. Motor filters have to be used if the
insulation strength of the motors and the maximum permissible voltage in the motor
terminal box does not reach the required value of 1300 V and the permissible rate of
voltge rise and winding insulation is < 3 kV/µs.
