5.3.2 Caution for REC System
Described below is a caution in REC System use.
● The EC connection unit occupies domains for four axes (one word) even though not all of four
axes are connected. Also, an axis number that an axis is not connected should not be pulled
one number forward.
● SIO connector on ELECYLINDER connected to the EC connection unit cannot be used.
● The jog switch on the EC connection unit should perform forward end and rearward end
movements with the data set in the position data. It should perform the home-return operation
before an operation to both forward and rearward end movements if the home-return
operation is not completed.
● As the jog switch to be activated/inactivated should be set in the gateway parameter, the
setting should be reflected to all the EC connection units at once.
● If the deadman’s switch on a teaching pendant connected to the EC gateway unit is set
disabled, ELECYLINDER gets into the motor voltage drop condition.
● The time spent during a movement command (ST* Signal) sent from the PLC reaches the EC
gateway and then sent to the EC connection unit, and a command is issued to
ELECYLINDER should take approximately 20ms.
● A command from a teaching pendant may delay for 40ms or more at maximum in one time of
communication in some conditions of REC System.
● When ELECYLINDER equipped with a Digital Speed Controller is connected to the EC
connection unit;
1) the screen would not be able to move to the trial run window for the Digital Speed
Controller if the mode switch on the EC gateway unit is set AUTO.
2) the trial run window on the Digital Speed Controller should close if the mode switch on the
EC gateway unit is set MANU → AUTO while the trial run window is kept open.
● When a window to operate an actuator is open on a teaching tool or a Digital Speed
Controller, an operation by the jog switch should not be available. When a window to operate
an actuator get open on a teaching tool or a Digital Speed Controller during an operation by
the jog switch, the actuator should decelerate and stop.
* If the communication gets disconnected while a window to operate an actuator on a teaching
tool, an operation by the jog switch should be kept prohibited. In order to set it back to the
condition that an operation by the jog switch is available, have either of rebooting the power,
connecting the teaching tool again, having the window to operate the actuator open and
closed, or conducting the software reset on ELECYLINDER. (It will not have the jog switch
kept prohibited if ELECYLINDER is equipped with a Digital Speed Controller.)
● Switching from MANU to AUTO while an operation command being input from the PLC should
allow the command signal accepted and make operation.
Turn an operation command off when set to MANU or stopping a program so it would not start
operating at the timing to switch from MANU to AUTO.
