1.2.1.4 ROBOT DOES NOT MOVE
This condition exists when the robot does not move when conditions are set for teach or
repeat mode.
Main causes include:
1. External hold condition exists.
2. An error condition exists.
3. Operation panel switches set incorrectly.
4. Motor brakes are not released.
5. If the check mode is selected, ensure an enabling device is engaged and the GO
(step forward) key is pressed.
6. Robot is waiting for input signals in repeat mode (cycle start, step forward, program
change, WX, JUMP, etc.)
Release external hold condition.
If the operation panel error lamp is illuminated or an error message is displayed on
the teach pendant LCD, take appropriate measures to release the error condition
according to the error message.
Ensure the operation panel switches are set correctly for robot operation.
Ensure proper brake voltage is available to the brake release circuit. Check and
repair poor connections, disconnected connectors, open wiring, short circuited wiring,
or any abnormalities in the brake circuits. Ensure the 1KP board, 1KQ/1NR board,
AVR power supply, MC unit, 1KQ/1NR board, servo motor, and controller internal
brake harnesses are in serviceable condition.
When check mode is selected, ensure an enabling device is engaged and the GO
(step forward) key is pressed.
In repeat mode, ensure input signals are received to release a wait condition.
! WARNING
The robot may move suddenly when a wait condition is
released. Do not approach the robot when it appears to
be stopped.
