4.2 Analog Input (AI) Object Descriptions

Object AI-1:

Actual Frequency

This object represents the actual speed of the drive in Hz.

Object AI-2:

Command Frequency

This object represents the commanded drive speed in Hz.

Object AI-3:

Load Percent

This object represents the drive’s load current as a % of rated current.

Object AI-4:

Total Runtime

This object represents the number of hours that the drive has been running since its first
power-up.

Object AI-5:

DC Bus Voltage

This object represents the drive's DC Bus Voltage as a percentage of the nominal DC bus
voltage.

Object AI-6:

PID Setpoint Command

This object is for monitoring the commanded PID Setpoint. The range of this object is
defined by Drive Parameter #75 (Feedback @ Min) and Drive Parameter #76 (Feedback @
Max).The unit is %.

Object AI-7:

PID Feedback

This object is for monitoring the current PID Feedback value at the input specified by Drive
Parameter #74 (PID Feedback). The range of this object is defined by Drive Parameter #75
(Feedback @ Min) and Drive Parameter #76 (Feedback @ Max).The unit is %.

4.3 Analog Value (AV) Object Descriptions

Object AV-1: Keypad Speed Command

This object monitors and controls the Keypad Speed Command (in Hz). The ability to
command this object through the LAN is dictated by the setting of Drive Parameter #30
(Control) and the drive’s current H/O/A Mode (Refer to Object MSI-4).

Object AV-2: Keypad Setpoint Command

This object monitors and controls the Keypad Setpoint Command. The unit for this object
is percent (%). The minimum and maximum values for this object are defined by Drive
Parameter #75 (Feedback @ Min) and #76 (Feedback @ Max), respectively. The range of
adjustment for Drive Parameters #75 and 76 is –32768 to 32767.

The ability to command this object through the LAN is dictated by Drive Parameter #30
(Control) and the drive HOA (Refer to Object MSI-4).
