Programmable relay outputs
As standard there are three programmable relay outputs. Six outputs can be added
by using the optional digital I/O extension modules. By means of a parameter
setting, you can choose which information to indicate through the relay output:
ready, running, fault, warning, motor stall, etc.
The standard relay output’s RO1, RO2 and RO3 are configured to the brake open,
running and inverted faults, respectively, as shown below.
Par. 14.01 RO PTR1 is configured default for brake open as +003.013.06
(Par. 03.13 bit 6)
Par. 14.02 RO PTR2 is configured default for running as +003.002.02
(Par. 03.02 bit 2)
Par. 14.03 RO PTR3 is configured default for inverted fault as -003.002.03
(Par. 03.03 bit 3)
It is possible to write a value to a relay output through a serial communication link.
