Once you have entered the password, you enter MO=1 to initiate “motor on” state, in which
you can run controller reference commands. If no motor is connected to the
SimplIQ
drive,
the drive may refuse to accept MO=1, claiming that all Hall sensors read the same. In such a
case, you may use one of the following remedies:
Set CA[28]=1 to define a DC motor that does not require Hall sensors.
Change CA[1] so that one Hall sensor is software-inverted.
Define CA[20]=0, “No Halls are present.”
To restore under-voltage protection, enter:
TW[34]=1024
Notes:
To run simulation only, disconnect the power supply from the
SimplIQ
drive. If a
motor and a power supply are connected to the drive, the motor will run normally,
despite TW[34].
When TW[34]=0, an auto-phasing process will indicate success and continue to
MO=1 regardless of its actual success. Do not set TW[34]=0, CA[20]=0, MO=1 with
the motor and power supply connected because the auto-phasing process can fail
without being noticed, resulting in unstable feedback control.
7.2.2 Applying Digital Inputs without Connecting to an
Input Device
The IL[N] command defines the functionality of the digital input pin. IL[1] defines the
behavior of digital input #1, IL[2] defines the behavior of digital input #2 and so on. In
addition to the pin functionality, the IL[N] command defines if the corresponding digital
input signal is read from the hardware or if it is software simulated. For details, refer to the
IL[N] command section of the
SimplIQ
Command Reference Manual.
7.2.3
Applying a Motor Fault
In order to test exception handling, you can simulate a motor fault by entering:
TW[32]=n (password protected)
The
SimplIQ
drive will abort the “motor on” (MO=1) state and the motor fault (MF) report
will be n.
7.2.4 Applying a Follower Reference without Connecting an
Encoder Signal to the Auxiliary Input
Using a simulated auxiliary encoder signal, you can test how your position follower or
ECAM or speed follower behaves without any external encoder connection. To do so, enter:
TW[35]=n (password protected)
