Set Pr. 73, Pr. 267, and a voltage/current input switch correctly, then input an analog signal
in accordance with the setting. Application of voltage with switch on (current input specifica-
tion) or current with switch off (voltage input specification) could lead to damage to the
inverter or analog circuit of external devices. (For details, refer to section 6.20.2.)

analog outputs
Description
Inputting 0 to ±5V DC or 0 to ±10V DC adds
this signal to terminal 2 or 4 frequency setting
signal. Use Pr. 73 to switch between the input 0
to ±5V DC and 0 to ±10V DC (initial setting).
Terminal 5 provides the common reference
potential (0V) for all analog set point values
and for the analog output signals CA (current)
and AM (voltage). The terminal is isolated from
the digital circuit's reference potential (SD).
This terminal should not be grounded. If local
regulations require grounding of the reference
potential note that this can propagate any
noise in the ground potential to the control
electronics, thus increasing sensitivity to inter-
ference.
