Control through the I/O interface using the step reference
logic/pendant control
This section describes how to set up the drive for control through the I/O interface
using the step reference logic/pendant control.
Safety
WARNING!
Obey all safety instructions for the drive. Only qualified electricians are
allowed to start up the drive.
Preliminary actions
Make sure that you have completed the basic start-up sequence of the drive. See
Start-
up, ID run and use
on page
23
.
Make sure that the motor control method is selected as vector control (
99.04
).
Power up the drive and wait for 10 seconds.
This is to make sure that all the boards are powered and the application is running.
Switch to local control.
Brake circuit check
Make sure that you can safely do the brake circuit check. For example, make sure that
the load is not hanging from a hook.
Make sure that the brake circuit is working as expected according to the command given
by the default brake control signal interface (relay output RO1):
• Open the brake temporarily by setting parameter
10.24
RO1 source
to
Energized
.
Verify that the brake opens.
• Set parameter
10.24
RO1 source
to
Brake command
to use the default brake control
signal interface.
Control signal settings
Select the signal sources for start and stop control.
