OPTIONAL CONFIGURATION SETTING:
GS2 mode is an
optional
setting for users who want the drive to operate in the legacy GS2 parameter
configuration. This mode changes the entire parameter structure of the drive. See the GS20 User Manual
Appendix G for more details.
Entering and Exiting “GS2” Mode
GS20 drives that have an equivalent GS2 model (same power and HP rating) have the option of being operated
in “GS2 Mode”. This allows you to use the new drive in exactly the same role as an older GS2 drive that needs
to be replaced, or in conjuction with existing GS2 drives.
Note that all drives will come factory standard with GS20 mode as the default setting.
Enter GS2 Mode
Note: To enter GS2 mode, parameters cannot be locked or set to read only, and the PLC must be disabled. If
any of these requirements are not met, you will be unable to set 00.02 to 20.
1) Set parameter 00.02=2, to reset to GS2 mode (step 1 of 2) and press ENTER.
2) Set parameter 00.02=20 to reset to GS2 mode (step 2 of 2) and press ENTER.
3) Reboot the drive by cycling power.
4) Configure GS2 parameters using the GS2 series User Manual.
Exit GS2 Mode
1) Set parameter 09.08=20 to reset to GS20 mode (parameters will reset). Press ENTER.
2) Reboot the drive by cycling power.
3) Configure GS20 parameters per the tables above and in the GS20 User Manual.

• External Flow Rate is across the heat sink.
• Internal Flow Rate is through the chassis.
• Published flow rates are the result of active
cooling using fans, factory installed in the
drive.
• Unpublished flow rates ( - ) are the result
of passive cooling in drives without factory
installed fans.
• The required airflow shown in the chart
is for installing a single GS20 drive in a
confined space.
• When installing multiple GS20 drives,
the required air volume would be the
required air volume for a single GS20 drive
multiplied by the number of GS20 drives.
• When calculating power dissipation (Watt
Loss), use the Total value. Heat dissipation
shown in the chart is for installing a single
GS20 drive in a confined space.
• When installing multiple drives, the volume
of heat/power dissipation should be the
heat/power dissipated by a single GS20 drive
multiplied by the number of GS20 drives.
• Heat dissipation for each model is calculated
by rated voltage, current and default carrier
frequency.
