Installation
Start-up
The ACH550 has default parameter settings that are sufficient for many situations.
However, review the following situations. Perform the associated procedures as
appropriate.
Spin motor
When first installed and started the control panel displays a welcome screen with the
following options.
• Press Exit to commission the drive as described in section Start-up by changing
the parameters individually on page 1-47 .
• Press Enter to move to the following options:
– Select “Commission Drive” to commission the drive as described in section
Start-Up by Start-up by using the Start-Up Assistant on page 1-47 .
– Select “Spin Motor” to operate the motor prior to commissioning. This option
operates the motor without any commissioning, except entry of the motor data
as described below. Spin Motor is useful, for example, to operate ventilation
fans prior to commissioning.
Note: When using Spin Motor, the motor speed is limited to the range 1/3…2/3 of
maximum speed. Also, no interlocks are activated. Finally, once the drive is
commissioned, the welcome screen and this option no longer appear.
Motor data
The motor data on the ratings plate may differ from the defaults in the ACH550. The
drive provides more precise control and better thermal protection if you enter the
rating plate data.
1. Gather the following from the motor ratings plate:
• Voltage
• Nominal motor current
• Nominal frequency
• Nominal speed
• Nominal power
2. Edit parameters 9905…9909 to the correct values.

(see page

editing instructions.
