4.8 Viewing Motor Measurement Values (Model PW3390-03 only)
100
Select the type of rotation signal to be applied to CH B
CHB input
Available setting items depend on the state of the following settings.
When [CHB input] is set to [AnalogDC], set these three items to suit the rotation signal: [CHB range],
[CHB scaling], and [CHB unit].
When [CHB input] is set to [Pulses], make these six settings to suit the rotation signal: [CHB unit],
[Max frequency], [No. of pulses], [Motor poles], [CHZ input] and [Phase Adjust].
Setting the Rotation Signal Input (CH B)
Analog DC For DC voltage proportional to the rotation rate
Pulses For pulse signals proportional to the rotation rate
When [Analog DC] is selected
CHB range Select to suit the applied rotation signal voltage input.
CHB scaling Settable from 0.01 to 9999.99. The measurement value displayed for CH B = CH B
input voltage × CH B scaling value. Set [CH B Units] according to the rotation rate
that corresponds to one volt of rotation signal.
CHB unit Always select r/min when measuring motor power (Pm).
1 V, 5 V, 10 V
V, Hz, r/min
• The CH B range can be selected with the current range keys from the Motor page of
the Measurement screen.
• Set the number of motor poles when measuring the slip. (p. 101)
When [Pulses] is selected
CHB unit Always select [r/min] when measuring motor power (Pm).
Hz, r/min
