5.9 Diagnostics
The following table shows the LED diagnostics displayed through the plastic dip-switch access
window (ref. A, page 35).
The drive makes a lot of messages available to the CNC (by means of error codes). These
messages can be managed and interpreted by the machine. For further information on CNC
diagnostics, refer to the User Manual “Diagnostics and Parameterisation” (for Smart Motors and
Drives) distributed by HSD S.p.A..
5.9.1 Meaning of the green led in the CANopen version
In standard mode, the green LED usually indicates the NMT status with regard to CANopen
communication. For this purpose, see paragraph “NMT state machine” in the “SM137D CANopen”
communication protocol user manual (Synchronous motor with built-in drive for the CANopen
Communication Protocol), distributed by HSD S.p.A..
It is also used to errors detected on start-up.
On the other hand, if an additional function has been selected (switch 6 On), the green led
indicates the bit-rate value that is currently set (see paragraph “Transmission speed setting (bit-
rate)” on page 42).
It is also used to signal an error by means of a rapid flashing light.
