Operating Instructions
4-Q-EC Servoamplifier DES 70/10
5.2.4 Status reading “Ready”
The “Ready” signal can be used to report operational readiness or a fault condi-
tion on a master control unit. The fault condition is stored. In order to reset the
fault condition, the servoamplifier must be re-released (Enable). If the cause of
the fault situation cannot be eliminated, the error will occur again immediately.
Additional external voltage is required:

Version 1:
Standard (pre-adjusted)
Error output
J403 short-circuited (0
Ω
)
J404 not mounted (open)
The open collector output is, in normal cases, i.e. no faults, switched to Gnd.
In case of a fault, the error output is not conducting (see also 6.2).
Version 2:
Special (customized)
Inverted error output
J403 not mounted (open)
J404 short-circuited (0
Ω
)
The open collector output is, in normal cases, i.e. no faults, not conducting (high
resistance).
In case of a fault, the error output is switched to Gnd (see also 6.2).
