Revolutions/Current
D-No. 500 Freerun Revolutions [rev.] Setting range: 0 ~ 99.9
The number of revolutions, from the start of fastening, at which switching to D-No. 402 [1st Speed]
is performed is set. However, even if the freerun revolutions are not reached, switching to D-No.
402 [1st Speed] is performed when D-No. 104 [Ramp D
own Start Torque] is detected. If “0.0” is set
as D-No. 500 [Freerun Revolutions], operation at the 1st speed is executed after operation at the
initial speed has been performed for D-No. 310 [Initial Time].
D-No. 501 Reverse Revolutions between 1-2 Step [rev.] Setting range: 0 ~ 99.9
This is the number of revolutions used in D-
No. 006 [Fastening Interrupt Operation]: “Reverse
Between 1-
2 Steps ON.”
D-No. 502 Reverse Revolutions between 2-3 Step [rev.] Setting range: 0 ~ 99.9
This is the number of revolutions used in D-
No. 006 [Fastening Interrupt Operation]: “Reverse
Between 2-3 Steps
ON.”
D-No. 503 Rundown Revolution Low Limit [rev.] D-No. 504 Rundown Revolution High Limit [rev.
]
Setting range: 0 ~ 99.9
The low and high limit values of the number of revolutions from the start of fastening to the end of
fastening are set.
If the number of revolutions at the end of fastening exceeds the rundown revolution high limit or
falls below the rundown revolution low limit, the REJECT Spindle judgment is made.
D-No.505 Reverse Revolutions before Fastening [rpm] Setting range: 0 ~ 99.9
This is the number of revolutions used in [Fastening Option]: “Reverse before Fastening.”
D-No.520 No Load Current Limit [%] D-No.523 Fastening Current Limit [%]
Setting range: 0 ~ 100
Set the current limit value to be used during the following operation.
By disconnection, control is made so that excessive torque is not generated under the
state where torque can not be detected.
D-No.520: "During initial speed ~ free run speed", "During reverse rotation"
D-No.523:
“During 1ST speed ~ fastening operation completed"
D-No.521 Low Current Warning [%] D-No.522 High Current Warning [%]
Setting range: 0 ~ 100
Warning is displayed by a user console. It is not displayed the warning to a controller.
