– 44 – 
circuit enters open status and the AC power to the servo power unit is turned off. 
The delay time of 500 ms is set by the safety relay module in the controller. 
  4.5.3  Restart Method 
  When the emergency stop switch is pressed, the safety relay module in the 
controller enters open status and error indication takes place. Be aware that servo 
ON enabled status is not entered. 
If 088-014 Emergency Stop SW ON and 008-281 Emergency SW relay ON occur 
concurrently, the safety relay module for emergency stop switch is not reset. Press 
RST-1 and RST-2 signals while all emergency stop switches are canceled. 
In TEACH mode, if the emergency stop switch is closed and the safety relay module 
is reset, the servo power circuit enters close status when the enable switch on the 
teach pendant is set to neutral. 
4.6  Fabricating SAFE Signal Cable 
  Follow the points below when fabricating the external I/O signal cable. 
  a.)  Use the connector supplied with the TSL3000E/TSL3100E robot controller for 
the SAFE connection connector. 
 
DFMC 1,5 ST-3,5-LR 
(plug-type connector) 
  b.)  Select the cable to be used based on the specifications below. 
    Core wires:  1.0 mm
2
 to 1.5 mm
2
 (AWG18 to AWG16) twisted wire, single 
conductor 
    Cable length:  30 m max. 
  Use of cables that do not match the specifications can result in a meltdown due to a 
short circuit or core wire overheating and also presents a danger of robot 
malfunction due to the intrusion of noise. Therefore, never use cables outside the 
specifications range. 
  c.)  The SAFE connector is of type where the connectors are joined by connector 
lock. See Para. 4.7 "Attaching and Detaching SAFE Connector."
