0 No cause
Any cause of no movement cannot be detected.
Normally moves.
1 Not in servo ready state.
• The main power of the servo driver has not been turned on.
• Some kind of errors is occurring.
• Synchronization between communication and servo is not
established.
• Processing in the attribute C parameter validation mode
according to the reset command.
And other
2 No servo-on command
The Servo On command is not given to the servo driver.
• Servo On bit of Command is 0.
• EX_ON (external servo-on input) is allocated and the signal is
off.
And others
3 Over-travel inhibit input active
• Pr.5.05 = 0,1 (Sequence at over-travel inhibit: other than
immediate stop) and Pr.5.04 = 0 (Over-travel inhibit input
active); and positive drive inhibit input (POT) is ON and
operation command is positive direction; or, negative drive
inhibit input (NOT) is ON and operation command is negative
direction.
• Pr.5.05 = 2 (Sequence at over-travel inhibit: immediate stop) and
Pr.5.04 = 0 (Over-travel inhibit input active); and positive drive
inhibit input (POT) is ON and operation command is positive
direction or negative drive inhibit input (NOT) is ON, causing the
operation to stop, regardless of operation command input.
4 Thrust limit value too small Valid thrust limit value is set to 5% or below the rated value.
7
Too low frequency of position
command input
Position command per control period is 1 command unit or smaller.
10
Instruction velocity through
RTEX communication is low.
The command velocity is set to 30 [mm/s] or below.
11 Manufacturer use –
12
Instruction thrust through RTEX
communication is low.
The command thrust is low: 5% or below the rated thrust.
13 Speed limit too low
• Pr.3.21 (Speed limit value is set to 30 [mm/s] or lower when
Pr.3.17 = 0.
• When Pr.3.17 = 1, the speed limit of the parameter (Pr.3.21 or
Pr.3.22) specified by SL_SW bit of the command is set 30
[mm/s] or lower.
14 Other causes
Causes 1 to 13 are met but the No. of revolutions is below 30
[mm/s]. (Too small commanded value, too heavy load, locking,
crashing, servo driver/motor failure, etc.)
*1) Even if any number other than 0, the motor may move.
*2) The position command generation process may be interrupted by over-travel inhibit input, resulting in detection of
cause 7 instead of cause 3.
