Setting the Input Range of the Torque Meter Signal Using the Channel Setting Menu
1.
Press the CH8 key to display the channel setting menu.
On products (PZ4000) with firmware version before 2.01 or when the motor module is
not installed in the element number 4 slot, the torque meter input range setting menu
does not appear.

2.
Press the [Sensor Range] soft key to display the input range selection box.
3.
Turn the jog shuttle to select the range from [50Vpk] to [1Vpk] and [Auto].
4.
Press the SELECT key to confirm the new input range.
Explanation
Signals from revolution sensors and torque meters can be input to channels 7 and 8 of
the PZ4000 for making measurements. For revolution sensors, the signal is the DC
voltage (analog signal) or the pulse count that are proportional to the rotating speed of
the motor. For torque meters, it is the DC voltage (analog signal) that is proportional to
the torque of the motor.
Selecting the revolution sensor signal type
Select from the following list of choices:
• Analog
Select this when the revolution sensor signal type is a DC voltage (analog signal).
• Pulse
Select this when the revolution sensor signal type is a pulse signal.
Selecting the input range of the revolution sensor signal
Two types of range settings are available: fixed range and auto range.
• Fixed range
• When the revolution sensor signal type is [Analog]
Select from the following input ranges:
50Vpk, 20Vpk, 10Vpk, 5Vpk, 2Vpk, and 1Vpk.
• When the revolution sensor signal type is [Pulse]
Fixed to 5Vpk.
• Auto range
Select [Auto] for the input range setting to enable auto range. The range changes
automatically depending on the amplitude of the input signal. The switching
conditions and precautions are the same as the descriptions given in section 5.3,
“Setting the Measurement Range during Direct Input.” The different ranges used in
the auto mode are the same as those available for fixed range.
