◆ Auto Mode Start/Stop Selection
Table 4.9 Auto Mode Start/Stop Selection
The iQpump drive offers four Auto Mode Start/Stop selections to start and stop the iQpump drive and to enable Auto mode operation.
The selections determined by the setting of parameters b1-01 and b1-02 are as follows:
Note: It is recommended to first select the system units and feedback device scaling. System units can be selected with
parameter P1-02 (system units) and feedback range can be set with parameter P1-03 (feedback device scaling).
Example:
P1-02 System Units = 1: PSI (lb/SqrInch)
P1-03 Feedback Device Scaling = 200 (200PSI)

DCInj Start Freq
Sets the frequency at which DC injection braking starts when ramp to
stop (b1-03 = 0) is selected. If b2-01< E1-09, DC injection braking
starts at E1-09.

P1-03 0602H
Feedback Device
Scaling
Fb Dev Scaling
Scaling of feedback device in user units (P1-02 = 1, e.g. 150PSI).
Digits 1 through 4 set the maximum feedback number. Digit 5
determines the number of decimal places.
Digit 5 = 0: Number format is XXXX
Digit 5 = 1: Number format is XXX.X
Digit 5 = 2: Number format is XX.XX
Digit 5 = 3: Number format is X.XXX
Examples:
01000 = 1000
13000 = 300.0
25000 = 50.00
32000 = 2.000
