Motor thermal relay OHS1 OHS2
OHS1
OHS2 are opened when heat is generated to an abnormal temperature.
Maximum rating: 125VAC/DC, 3A or 250VAC/DC, 2A
Minimum rating: 6VAC/DC, 0.15A
Earth terminal
For grounding, connect to the earth of the control box via the earth terminal of the servo
amplifier.
Note. There is no BW when the power supply of the cooling fan is a 1-phase.
