Pn04
Drive Prohibit Input Selection
Setting range 0 to 2
Explanation of Settings
Setting
0 Forward Drive Prohibit Input and Reverse Drive Prohibit Input enabled.
1 Forward Drive Prohibit Input and Reverse Drive Prohibit Input disabled.
2 Forward Drive Prohibit Input and Reverse Drive Prohibit Input enabled.
• Install limit switches at both ends of the axis to prohibit the Servomotor from traveling in the
direction specified by the switch. This can be used to prevent the workpiece from traveling too far
and thus prevent damage to the machine.
• Operation will be as follows if 0 is set.
• Connection between Forward Drive Prohibit Input (POT: CN1 pin 9) and COM closed: Forward
limit switch not operating and status normal.
• Connection between Forward Drive Prohibit Input (POT: CN1 pin 9) and COM open: Forward
drive prohibited and reverse drive permitted.
• Connection between Reverse Drive Prohibit Input (NOT: CN1 pin 8) and COM closed: Reverse
limit switch not operating and status normal.
• Connection between Reverse Drive Prohibit Input (NOT: CN1 pin 8) and COM open: Reverse
drive prohibited and forward drive permitted.
• If this parameter is set to 0, the Servomotor will decelerate and stop according to the sequence
set in the Stop Selection for Drive Prohibition Input (Pn66). For details, refer to the explanation for
Stop Selection for Drive Prohibition Input (Pn66) on page 5-88.
• If this parameter is set to 0 and the forward and reverse prohibit inputs are both open, an error will
be detected in the Servo Drive, and a drive prohibit input error (alarm code 38) will occur.
• If this parameter is set to 2, a drive prohibit input error (alarm code 38) will occur when the
connection between either the forward or reverse prohibit input and COM is open.
• If a limit switch above the workpiece is turned OFF when using a vertical axis, the upward torque
will be eliminated, and there may be repeated vertical movement of the workpiece. If this occurs,
set the Stop Selection for Drive Prohibition Input (Pn66) to 2 or limit operation using the host
controller rather than using this parameter.
Alarm Reset
Set the parameter to 0 for executing the alarm reset from the host controller and operating POT and
NOT inputs in the opposite direction when either POT or NOT is OPEN.
When the set value is 2, manually change the setting of POT or NOT input to close it and execute
the alarm reset to clear the alarm.
Pn05
Command Speed Selection
Setting range 0 to 3
Explanation of Settings
Setting
0 Speed Command Input (REF: CN1 pin 14)
1 No. 1 Internally Set Speed to No. 4 Internally Set Speed (Pn53 to Pn56)
2 No. 1 Internally Set Speed to No. 3 Internally Set Speed (Pn53 to Pn55) and Speed Command Input (REF)
3 No. 1 Internally Set Speed to No. 8 Internally Set Speed (Pn53 to Pn56 and Pn74 to Pn77)
• Use this parameter to select the speed command when using speed control. The Servo Drive has
internally set speeds that can be used to easily achieve speed control by using contact inputs.
• For details on internally set speeds, refer to 5-3 Internally Set Speed Control on page 5-5.
