Description
An alarm has occurred. Warning has occurred.
No reason has been detected. The motor operation should be
possible.
The main power supply to the driver is not turned ON.
The operation command (RUN) is not connected to COM.
When Pn504 = 0 (drive prohibition input enabled):
• The forward drive prohibition input (POT) is open and the speed
command is in the forward direction.
• The reverse drive prohibition input (NOT) is open and the speed
command is in the reverse direction.
The currently effective torque limit set value, Pn013 (No. 1 Torque
Limit) or Pn522 (No. 2 Torque Limit), is less than 5% of the rated
torque.
When Pn527 = 0 (analog torque limit scale):
• The forward analog torque limit input is negative and the speed
command is in the forward direction.
• The reverse analog torque limit input is positive and the speed
command is in the reverse direction.
Pn518 = 0 (command pulse prohibition input enabled) and the IPG
input is open.
• The command pulse is not input correctly.
• The input selected in Pn005 is not connected correctly.
• The type of input selected in Pn006 or Pn007 is not correct.
The position command per control cycle is 1 pulse or less and the
above are some of the possible causes.
Pn517 = 0 (Error counter reset at the level) and the error counter
reset input (ECRST) is connected to COM.
Pn315 = 1 (zero speed designation enabled) and the zero speed
designation input (VZERO) is open.
The analog speed command is 0.06 V or lower when the analog
speed command is selected.
The internal speed command is 30 r/min or less when the internal
speed command is selected.
The analog torque command input (REF or PCL) is 5% or less of the
rated torque.
• Pn317 = 0 (speed limit with No. 4 internally set speed) and the
No. 4 Internally Set Speed (Pn307) is 30 r/min or lower.
• Pn317 = 1 (speed limit with REF input) and the analog speed
command input (REF) is 0.06 V or lower.
