Drive cooling fan
The drive cooling fan is controlled by the temperature from monitoring
points and other actions as follows:
If the "hot" alarm is active or the IGBT temperature (Pr
7.34
) is greater
than the upper threshold then the fan will run at full speed. It will continue
to run at full speed until the IGBT temperature is below the lower
threshold. See the table below for the upper and lower thresholds.
If a Solutions Module indicates that it is too hot the fan runs at full speed.
The fan will continue to run at full speed for 10 seconds after the
Solutions Module has cooled down.
The fan can still be forced to run at full speed at all times if Pr
6.45
is set
to one. The fan will continue to run at full speed for 10 seconds after
Pr
6.45
has been set to zero.
For all other conditions the fan runs at low speed.

14.4.1 EtherCAT interface ID code
Table 14-7 EtherCAT interface ID code
This parameter is useful for checking the The EtherCAT interface is of
the correct type.
14.4.2 EtherCAT interface firmware version
Table 14-8 EtherCAT interface firmware version - (major and
minor)
Table 14-9 EtherCAT interface firmware version - (subversion)
The software version of the EtherCAT interface can be identified by
looking at Pr
17.02
and Pr
17.51
.
The software version takes the form of xx.yy.zz, where Pr
17.02
displays
xx.yy and Pr
17.51
displays zz, for software version 01.01.00, Pr
17.02
will display 1.01 and Pr
17.51
will display 0.
The full version of the EtherCAT interface firmware can be assembled by
combining the major version (xx.yy) and the minor version (zz) as
follows: xx.yy.zz.

StoP
Stop or holding zero speed
Enabled
The drive is holding zero speed.Regen> The drive is
enabled but the AC voltage is too low, or the DC bus
voltage is still rising or falling.
