Automatic motor tuning is not enabled. With regard to function "Auto tuning", the Automation Studio project
can be migrated without limitations.

Automatic motor tuning is performed for the ACOPOSinverter P64new during the first transition to state
"RUN" or "Operation enabled". In contrast to the ACOPOSinverter X64, the measurement is not repeated.

(LI4)
Automatic motor tuning is performed for the ACOPOSinverter P64new if the configured trigger is actuated.
In contrast to the ACOPOSinverter X64, the drive must be in state "RUN" or "Operation enabled" at the
time of the measurement and the bit of command STOP must be set.
6.6 Bit 11 of control word "CMDD" (direction reversal)
With the ACOPOSinverter P64new, bit 11 of control word "CMDD" can still be used for the direction reversal function
of the motor.
Notice!
In contrast to the ACOPOSinverter X64, bit 11 of control word "CMDD" can only be used for the direction
reversal function to change the direction of rotation of the connected motor if configuration parameter
[Rotating direction]
(rOt)
=
[Both]
(bOt)
has been configured.
Possible solution
The command to reverse the direction of the motor can only be executed via bit 11 of control word "CMDD" if the
bit was previously assigned a different function.
This behavior corresponds to the original product.
6.7 Bit 12 of command word "CMDD" (command STOP)
With the ACOPOSinverter P64new, bit 12 of command word "CMDD" can still be used to stop the motor.
Notice!
Specification DS 402 requires that bit 8 of the command word initiates command STOP. The deviating
behavior of the original product was applied to the replacement product.
This behavior corresponds to the original product.
6.8 Resetting the parameter set (control word "CMI")
With the ACOPOSinverter P64new, the command for resetting the parameter set can still be used via bit 0 of control
word "CMI". The command must be extended, however.
The ACOPOSinverter P64new is based on a different drive variant. Some values of the default parameter set differ
from the ACOPOSinverter X64. To reproduce the original default parameter set, command "Reset to default" must
be added.
A special firmware has been developed for the communication card of the ACOPOSinverter P64new that carries
out all known adjustments after resetting the parameter set when the drive is started. To trigger a restart with the
ACOPOSinverter P64new, register "RP" can be used.

2
Enable reference change
Write "TRUE" to bit 15 of CMI_Output
3

Write 167 to FR1_Output
4
Write "Restart device"
Write "TRUE" to bit 0 of RP_Output
5
