4.2.5 OPTAF board parameter
Code Parameter Default Note
P7.2.1.1 Therm Trip
(HW)
Refer 4.2.4
“On” Correct settings:
• "Jumper wire X12 not cut and this board parame-
ter "On" (for ATEX)
• "Jumper wire X12 cut and this board parameter
"Off" (for
no ATEX and similar to OPT-A3)
Wrong settings:
• "If jumper wire X12 is cut and this board parameter
is "On", thermistor trip will cause unresettable
System Fault 8, subcode 41.
• "If jumper wire X12 is not cut and this board
parameter is "Off", thermistor trip will cause unre-
settable System Fault 8, subcode 48.
P7.2.1.2 Start-Up Prev “Fault” To start the motor operation after the STO safety function
or a thermistor fault, an edge sensitive start command is
required after the drive returns to ready state.
a) When OPTAF board parameter "Start-Up Prev"
is "
Fault ", the drive will generate a "F26 Start-
Up Prev" fault if start command is on , when
returning to ready state after the STO safety
function or a thermistor fault has been active.
The drive can be started with an edge sensitive
start command after fault reset.
b) When OPTAF board parameter "Start-Up Prev"
is "
Warning ", the drive will generate a "A26
Start-Up Prev" warning if start command is on ,
when returning to ready state after the STO
safety function or a thermistor fault has been
active. The drive can be started with an edge
sensitive start command. No fault reset is
required in this case.
c) When OPTAF board parameter "Start-Up Prev"
is "
No action ", the drive will not generate any
indication. The drive will start with any start
command immediately after the STO safety
function or thermistor fault. No fault reset is
required in this case.
