Factor No.
An error is occurring, and an alarm is triggered.
No factor is detected for No-motor run.
The motor runs in normal case.
The main power of the driver is not turned on.
The Servo-ON input (SRV-ON) is not connected to COM–.
While Pr04 is 0 (Run-inhibition input is valid),
• CCW over-travel inhibition input (CCWL) is open and speed command is CCW direction.
• CW over-travel inhibition input (CWL) is open and speed command is CW direction.
Either one of the valid torque limit setup value of Pr5E (1st) or Pr5F (2nd) is set to 5% or
lower than the rating.
While Pr03 is 0 (analog torque limit input accepted),
• CCW analog torque limit input (CCWTL) is negative voltage and speed command is CCW
direction.
• CW analog torque limit input (CWTL) is positive voltage and speed command is CW
direction.
Pr43 is 0 (Command pulse inhibition input is valid.), and INH is open.
The position command per each control cycle is 1 pulse or smaller due to,
• No correct entry of command pulse
• No correct connection to the input selected with Pr40.
• No matching to input status selected with Pr41 pr Pr42.
While Pr4E is 0 (Deviation counter clear at level), the deviation counter clear input (CL) is
connected to COM–.
While Pr06 is 1 (Speed zero clamp is valid.), the speed zero clamp input (ZEROSPD) is
open.
While the analog speed command is selected, the analog speed command is smaller than
0.06[V].
While the internal speed command is selected, the internal speed command is set to lower
than 30 [r/min]
The analog torque command input (SPR or CCWTL) is smaller than 5 [%] of the rating.
• While Pr5B is 0 (speed is limited by 4th speed of internal speed), Pr56, (4th speed of
speed setup) is set to lower than 30 [r/min].
• While Pr5B is 1 (speed is limited by SPR input), the analog speed limit input (SPR) is
smaller than 0.06 [V].
The motor runs at 20 [r/min] or lower even though the factors from 1 to 13 are cleared,
(the command is small, the load is heavy, the motor lock or hitting, driver/motor fault etc.)
