APPENDIX A: Using the Varispeed motor controller
(YASKAWA - J1000)
The motor controller is used to give the machine a soft start, control the
speed, protect the motor against overload and to indicate certain faulty
conditions on the machine.
1. Programming
The Yaskawa 1.5kW controller has a large number of
programmable parameters affecting its operation, each with a
factory default value. Some of these parameters have been
changed from the default values as indicated below. To change
any parameter value proceed as follow:
With the machine stationary, press the “V” key once. The
digital operator shows the parameter menu (PAR) then press
“ENTER” key. Press the “>” key to select the digit/parameter
you would like to change. Next use the “
Ʌ
” and “V” keys to
select the parameter group, sub-group or number. Modify the
parameter value using the “
Ʌ
” and “V” key and press the
“ENTER” key to save the new value.
2. Basic operation
The motor speed is set as follows:
To adjust the speed, which is displayed in frequency units “Hz”,
adjust the “SPEED” knob in the orange control box marked zero
to ten.
Max. possible speed is set at 48 Hz, at which speed exactly 2
wheels per sec. passes a fixed point (7200 wheels per hour). If
you try to adjust the speed higher than 48Hz the display will
flash and go back to the previous saved value. When the light at
the LO/RE key is on (local/remote) then it is possible to run and
stop the machine by the “RUN” and “STOP” keys on the
controller itself. If the light is off then it is only possible by the
green and red buttons on the outside of the control unit.
