Relationship between the Torque Signal Pulse Input Range and Pulse Rating
To measure a torque of –20 N•m to +20 N•m using a torque meter with specifications in the figure below,
configure the pulse input range and pulse rating settings as indicated below.
• Upper limit of the pulse input range (Pulse Range Upper): 20.0000
• Lower limit of the pulse input range (Pulse Range Lower): –20.0000
• Positive rated torque signal value (Rated Upper): 50.0000
• Negative rated torque signal value (Rated Lower): –50.0000
• Positive rated torque signal pulse frequency (Rated Freq Upper): 15000
• Negative rated torque signal pulse frequency (Rated Freq Lower): 5000

Pulse rating (positive): 15 kHz is output at a torque
of 50 N•m
Pulse rating (negative): 5 kHz is output at a torque
of –50 N•m
The pulse input range setting applies to input signals whose type has been set to pulse. For input signals
whose type has been set to analog, there is no need to configure this setting.
