Operation
■
Stopping the Motor
• When finished operating the motor in the no-load state, press the STOP/RESET Key. The motor will
stop.
After checking the operation with the motor in no-load status, connect the mechanical system and
operate with an actual load using the Digital Panel keys.
• Confirm that the motor has stopped completely before connecting the mechanical system.
• Be sure to tighten all the screws when connecting the motor axis to the mechanical system.
• If an error occurs during operation, immediately press the STOP/RESET Key on the Digital Opera-
tor.
• First set the frequency reference to a low speed of one tenth the normal operating speed. (Set the
frequency reference somewhat lower than the actual operating speed.)
■
Checking the Operating Status
• Check that the operating direction is correct and that the machine is operating smoothly at slow
speed before increasing the frequency reference.
• After changing the frequency reference or the rotation direction, check that there is no vibration or
abnormal sound from the motor. Check the monitor display to confirm that the output current is not
becoming excessive.
• Refer to 3-4-4 Selecting Forward or Reverse Operation for information on forward/reverse operation
selection. If parameter initialization (P20) is performed, reverse operation will be prohibited (P13).
To change the direction of rotation for actual load operation, enable reverse operation (P13). Refer
to
3-6-9 Selecting Reverse Rotation Prohibition for information on the reverse rotation prohibit
selection (P13).
