Enable seq error enable input circuit, TB 12, is closed the enable input can not be tied to +24 V with
before the drive is finished powering up. parameter [main commands = terminals] while the
drive powers up. This is to prevent unintentional
automatic restarting.
External fault external fault circuit, TB point 15, is control circuit is open
open circuit, not tied to +24 V blown 24 V fuse
Overcurrent overcurrent setting is too low check parameter [ overcurrent thr ]
current regulator is mistuned check Eint and regulator tuning
short circuit or ground fault in armature circuit check motor circuit integrity
Field loss no field current blown fuse in field package AC input
field current parameters are wrong
open field circuit
field current below min field settings check min field setting, field weakening
parameters
unstable flux regulator, check output current
stability and parameters [Flux P], [Flux I ],
[voltage P gain], [voltage I gain]
Speed fbk loss loss of encoder input check encoder power supplies, connections, and
wiring
check encoder jumper settings
misadjustment of encoder loss detection
misadjustment of [enable fbk contrl] parameters
Opt2 failure DGF card failure Option 2 is enabled with the DGF card ribbon
cable disconnected. Card is failed
DGF software error A software error has occurred, for instance, a
divide by zero error.
Improper DGF card parameter settings have been
entered.
Reset the DGF card using jumper S17, also trying
cycling power.
Bus loss Problem with the bus wiring check wiring, termination resistors, etc...
excessive noise on the bus check wiring, grounding practices
improper bus configuration check bus info, data size, data type, addressing,
configuration data
replace card
Opt 1 failure bad option 1 card replace card
