Chapter 6 Fastening Operation
PAGE 6-72
Revolutions/Current
D-No. 500 Freerun Revolutions [rev.] Setting range: 0 ~ 99.9
Sets the number of revolutions before D-No.401 [Freerun Speed] is switched to D-No.402 [1
ST
Speed].
Even if the Freerun Speed Revolution is not reached, it switches to D-No.402 [1
ST
Speed] when the
D-No.104 [Ramp Down Start Torque] is detected.
If “0.0” is set for D-No. 500 [Freerun Revolutions], operation at the 1st speed is executed after
operation at 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 for 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 for 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
Sets the low and high limit values for the number of revolutions rotated from the start of fastening to
the end of fastening.
If the number of revolutions at the end of fastening exceeds the rundown revolution high limit or falls
below the rundown revolution low limit, a REJECT judgment is made.
D-No.505 Reverse Revolutions before Fastening [rpm] Setting range: 0 ~ 99.9
This is the number of revolutions used for [Fastening Option]: “Reverse before Fastening.”
D-No.520 No Load Current Value [%] D-No.523 Fastening Current Limit [%]
Setting range: 0 ~ 100
Sets the current limit value which limits the amount of current output during the following
operations;
D-No.520: Limits output current during ‘initial speed ~ free run speed’ and during reverse
rotation
D-No.523: Limits output current during ‘1ST speed ~ until fastening operation is
completed"
By setting a value lower than 100%, max. torque will be limited (to the percentage input
in the D-No 520 or 523 operation)
D-No.521 Low Current Warning [%] D-No.522 High Current Warning [%]
Setting Range：0 ～ 100
The Current Warning low/high signals can currently only be used when using the integrated PLC
function
