The following table shows the error details and remedies to be taken when an error
occurs.
Hardware is faulty.
Start was made when the QD70 was not ready.
A start request was given when the axis stop signal
(Y10 to Y17) is ON.
• Positioning control was carried out in a position in
excess of " Pr. 1 Software stroke limit upper limit
value".
• "Md. 1 Current feed value" or " Da. 6 Positioning
address/movement amount" (New current value) has
exceeded " Pr. 1 Software stroke limit upper limit
value".
• Positioning control was carried out in a position in
excess of " Pr. 2 Software stroke limit lower limit
value".
• "Md. 1 Current feed value" or " Da. 6 Positioning
address/movement amount" (New current value) has
exceeded " Pr. 2 Software stroke limit lower limit
value".
The PLC READY signal (Y0) turned OFF during
operation.
The PLC READY signal (Y0) turned OFF immediately
after turning ON.
With "OPR. 1 OPR method" being any of near-point
dog method, count 1 and count 2, machine OPR
control was started when the near-point dog was ON.
With "OPR. 1 OPR method" being either of stopper 2
and stopper 3, the zero signal is input when machine
OPR control is started.
Fast OPR control was started though machine OPR
control was not yet carried out.

or JOG operation, the axis decelerates to a
stop as soon as "Md. 1 Current feed value"
exceeds the software stroke limit range.
• During position control (including position
control of speed-position switching control),
the axis decelerates to a stop as soon as
"Md. 1 Current feed value" or " Da. 6
Positioning address/movement amount"
