Control Options
Hand/Auto Controls
The drive can be operated in either
HAND
or
AUTO
mode as follows:
•
HAND
mode runs the motor based on
Hand Speed Ref [SET–09]
(frequency source) and
Hand
Run Cmd [SET–10]
(command source). The default for both settings are Keypad, which runs
the motor at a fixed speed (Keypad Setpoint) set on the Home Screen. Both settings can
be reprogrammed for external control. PID control is disabled in Hand mode.
•
AUTO
mode runs the motor based on
AUTO Speed Ref [SET–07]
(frequency source) and
AUTO
Run Cmd [SET–08]
(command source). The speed reference default is set per application.
The run command default is Keypad. Both settings can be reprogrammed as required.
There are several options to consider for operation of the VFD through external HOA controls:
HOA Mode Source [SET–60]:
Selects whether Hand/Auto control will come from the Key
-
pad, a Digital Input, or Communications. When switching modes with the keypad, the VFD
will stop and then will start again when the
START
key is pressed. When switching modes with
a DI or Comm source, the VFD will start based on the presence of a run command.
•
Keypad (Default):
The VFD Keypad HOA buttons, including
START
and
STOP
, are fully
functional.
•
Digital Input:
Enables HOA control through an external switch wired to two digital
inputs (MI1 to MI8). These inputs should be set to
26_HOA Hand
and
27_HOA Auto
through
parameters
[IO–21]
to
[IO- 28]
. HOA mode is then determined as follows:
•
RS485 Serial:
Enables HOA control through Modbus communications.
•
Com Card:
Enables HOA control through BACNet communications. The combinations of 0x2002 bit 3
and bit 4 are defined as follows:
KPD STOP as OFF [SET–61]:
When enabled, the Stop key acts as a keypad HOA OFF mode, stopping the
VFD from being controlled by anything other than an External HOA. To return to Auto or Hand mode, press
the corresponding key.
Hand Speed Ref [SET–09]:
Source of Speed Reference in Hand mode. When in Hand mode, PID is disabled
and the VFD frequency is based on the following inputs:
•
Keypad (Default):
VFD runs at a fixed frequency set on the Home Screen.
•
RS485 Serial:
Frequency input through Modbus control.
•
AVI1 Analog
: Inputs from external controller, potentiometer, or other device.
•
ACI Analog
: Inputs from external controller, potentiometer, or other device.
