 Note!
Exchange of devices
When devices with a parameterised servo control for asynchronous motors are
exchanged, problems regarding the control quality may occur if motor parameters set
for a device lower than version 11.00.00 are transferred to a replacement device of a
higher version.
• In this case, we recommend to load the very precise motor data available from
»Engineer« V2.17 or to execute the "advanced motor parameter identification"
(C02867/1
=2).Automatic motor data identification ( 141)
• As an alternative, the slip calculation from the motor nameplate data can be set again
in C02879/1
(bit 1 = "0") to obtain the previous behaviour.
