10.2.5 Delay circuit
We offer two paths, with or without delay circuit between safety input 1(HGWOFF1)/safety input
2 (HWGOFF2) input circuit and servo motor current control signal blocking circuit. When using in
vertical axis, please use path with delay circuit to prevent motor shaft falling due to holding brake
operation delay during safe torque off function operation.
✔
Even the hardware without delay circuit, there are still max. 20ms of delay until the safe
torque off function works due to the delay in the input circuit.
✔
Holding brake excitation signal and servo motor holding brake are not safety related parts.
