Altivar® 58 TRX AC Drives
Type FVC Analog and Logic Outputs
ATV58 TYPE FVC ANALOG OUTPUTS
Signed Ramp (Code ORS)
When configured for signed ramp, the analog output provides a signal proportional to the drive controller’s internal frequency ramp. This output is scaled to indicate rotation direction. AOL corresponds to the maximum frequency (parameter tFr) in the reverse direction. AOH corresponds to the maximum frequency (parameter tFr) in the forward direction. (AOH + AOL) divided by 2 corresponds to zero frequency.
PID Setpoint (Code OPS)
The image of the PID regulator setpoint. AOL corresponds to the minimum setpoint. AOH corresponds to the maximum setpoint.
PID Feedback (Code OPF)
The image of the PID regulator feedback. AOL corresponds to the minimum feedback. AOH corresponds to the maximum feedback.
PID Error (Code OPE)
The image of the PID regulator error as a percentage of the sensor range (maximum feedback minus minimum feedback). AOL correspond to
PID Integral (Code OPI)
The image of the PID regulator error integral. AOL corresponds to LSP. AOH corresponds to HSP.
ATV58 TYPE FVC LOGIC OUTPUTS
The programmable relay, R2, on the drive controller or the programmable logic output, LO, on an I/O extension card can be configured for the following additional functions:
PID Error (Code PEE)
Can be assigned to R2 or LO. The logic output is active (state 1) or the relay is energized if the PID regulator output error is greater than the threshold set by parameter PEr.
PID Feedback Alarm (Code PFA)
Can be assigned to R2 or LO. The logic output is active (state 1) if the PID feedback moves outside the range set by parameters PAH and PAL.
