This section describes pump operation. Observe instructions in this manu-
al. See manufacturer's instruction manual for the motor driver.
Pump setting
First, program operation of the pump.
Pulse input direction & Motor rotation
The pump lets out liquid at the input of the CCW direction command pulse and takes in liquid at the input of the
CW direction command pulse.
The motor-driven cylinder is at the origin at factory default setting. Before operation, use a tester to check an
output of the home sensor is at the “L (GND)” level.

The above data is based on the assumption that the driver is set to half step with the motor-driven cylinder at the origin.
Actual discharge capacity varies with a piping condition or so.
The lower limit of the motor-driven cylinder
NOTE
Do not move the motor-driven cylinder over the lower limit.

Observe the lower limit, which comes to a clock-
wise rotation for 600 pulses from the ON position
