ACH580-01 Installation
8. Before Start-up
Prepare for start-up by reviewing the following information. The First start assistant
walks you through the initial start-up procedure.
Motor data
The motor data on the ratings plate may differ from the defaults in the ACH580. The
drive provides more precise control and better thermal protection if you enter the
rating plate data.
Before start-up, gather the following from the motor ratings plate:
• Nominal motor current
• Nominal speed
• Voltage
• Nominal frequency
• Nominal power
Default configurations
After initial start-up, you will need to complete the commissioning. This will
determine how the drive is controlled, let you make use of default configurations,
and allow you to change specific parameters. See
.
The ACH580 can be controlled by two default configurations.
HVAC default direct I/O control –
Used for typical I/O controlled BMS applications.
• In the Auto mode, this configuration uses a direct speed reference connected to
analog input 1 (AI1).
• In the Hand/Off mode, the speed reference and start command are given through
the control panel (operator keypad).

PID control, single motor –
Offers quick setup of PID control for keeping flow or
pressure constant, requiring feedback from the process given by a feedback signal
connected to analog input 2 (AI2).
• You can set a constant setpoint, or, in the Auto mode, you can specify the
setpoint to come from analog input 1 (AI1) or from the control panel.
• In the Hand/Off mode, the speed reference and start command come from the
control panel.
• In the Hand mode, the speed reference is the direct speed reference and a PID
setpoint value.
