7.2 Digital Outputs

Error: Monitoring Output

Whenever a system failure occurs (i.e. overtemperature), the Error output responds (LO

position), and the green LED on the front panel is switch to red. The drive output stage is

switched off and the error will not reset until the user resets the drive by switching the

enable input. If the error occurs again the problem still exists.

The output is an open-collector output and via an external pull-up resistor adaptable to the

most industrial logics, up to +30 V.

Additional information about the schematic refer chapter 3.2.

Range of Output Voltage min. 0.4 V at LO – max. 30 V at HI

Output Impedance >100 Ohm at LO

Permanent Output Current 20 mA max.

Note:

The logical state of this output is clearly visible by the green/red OK/Fault LED on

the front panel.

Ready: Monitoring Output

The Ready output is set if there no errors occurs in the drive (LO position). On error the

output is opened and will not reset until the user resets the drive by switching the enable

input. This output is a mirror image of the Error output.
