○ ○ ○ ○
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 Pr5.04 is 0 (Run-inhibition input is valid),
• Positive direction over-travel inhibition input (POT) is open and speed
○ ○ ○ ○
command is Positive direction.
• Negative direction over-travel inhibition input (NOT) is open and speed
command is Negative direction.
Either one of the valid torque limit setup value of Pr0.13 (1st) or Pr5.22
○ ○ ○ ○
(2nd) is set to 5 % or lower than the rating.
While Pr5.21 is 0 (analog torque limit input accepted),
• Positive direction analog torque limit input (P-ATL) is negative voltage
○ ○ ○
and speed command is Positive direction.
• Negative direction analog torque limit input (N-ATL) is positive voltage
and speed command is Negative direction.
○ ○
Pr5.18 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 Pr0.05.
• No matching to input status selected with Pr0.06 pr Pr0.07.
While Pr5.17 is 0 (Deviation counter clear at level), the deviation counter
○ ○
clear input (CL) is connected to COM–.
While Pr3.15 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 P-ATL) is smaller than 5 [%]
○
of the rating.
• While Pr3.17 is 0 (speed is limited by 4th speed of internal speed),
Pr3.07, (4th speed of speed setup) is set to lower than 30 [r/min].
○
• While Pr3.17 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/
