3.4 Motion Parameter Details
3.4.3 Monitor Parameter Details
 Bit 4: Motion Command Setting Error
0: No command setting error.
1: Command setting error.
This bit changes to 1 when an unusable motion command is set.
 Bit 6: Positive Overtravel
0: No positive overtravel.
1: Positive overtravel occurred.
This bit changes to 1 when positive overtravel is disabled in the fixed parameter settings and a
positive overtravel signal is input.
Positive Overtravel Warning Signal
The positive overtravel warning signal turns ON when all of the following conditions are met.
• SERVOPACK Parameter Settings
Pn50A is H2881 (P-OT is valid when CN1-8 is at the low level).
Pn50B is H8881 (N-OT is valid when CN1-7 is at the low level).
• Fixed Parameter Settings
Bit 3 in fixed parameter No. 1 is 0 (Disabled).
Bit 4 in fixed parameter No. 1 is 0 (Disabled).
• The power supply to the Servomotor is ON (Servo ON).
• A motion command such as POSING (Positioning) or FEED (Jog) is executed.
• The reference is in the P-OT or N-OT direction.
• The SERVOPACK's P-OT or N-OT input signal turns ON.
 Bit 7: Negative Overtravel
0: No negative overtravel.
1: Negative overtravel occurred.
This bit changes to 1 when negative overtravel is disabled in the fixed parameter settings and a
negative overtravel signal is input.
Negative Overtravel Warning Signal
The negative overtravel warning signal turns ON under the same conditions as the positive
overtravel warning signal.
 Bit 8: Servo ON Incomplete
0: Servo ON.
1: Servo ON incomplete.
This bit is 1 if the Servomotor's power is not ON, even if bit 0 (Servo ON) in the OW00
setting parameter is set to 1.
 Bit 9: SERVOPACK Communications Warning
0: Communications normal.
1: Communications error detected.
This bit changes to 1 when an error occurs in communications with the slave SERVOPACK.
This bit is cleared automatically when communications are restored to normal operation.
