Cause : Smart Mode not supported comes when the power unit does not support the Smart Mode. Set the suitable sampling time 250 μs <= p0115[0] <= 400 μs (e.g. by setting p0112 and p0115 to the factory setting). Upgrade the power unit software and/or hardware for the Smart Mode. The availability of the Smart Mode function is displayed in r0192.

- for A_INF the following applies: De-activate the Smart Mode with p3400.0 = 0 and activate the voltage control with p3400.3 = 1. For booksize power units, it must be noted that for a supply voltage p0210 > 415 V only the Smart Mode is possible in the pre-setting. If DC link voltages above 660 V are permissible in the application, then voltage- controlled operation can be activated with p0280, p0210, p3400 and p3510. The information regarding p0210 should be carefully noted.
