1. Specify Shutdown in controlword (6040h, bits 0 to 3) to reset the Servo Drive.
2. Specify Switch ON and the Servo ON command (Enable Operation command) in
controlword (6040h, bits 0 to 3).
Power will be supplied to the motor.
12.3.6 Detecting Errors in HWBB Signal
If only the /HWBB1 or the /HWBB2 signal is input, an A.Eb1 alarm (Safety Function
Signal Input Timing Error) will occur unless the other signal is input within 10 seconds.
This makes it possible to detect failures, such as disconnection of an HWBB signal.
CAUTION!
The A.Eb1 alarm (Safety Function Signal Input Timing Error) is not a
safety-related element. Keep this in mind when you design the system.
12.3.7 HWBB Input Signal Specifications
If an HWBB is requested by turning OFF the two HWBB input signal channels (/HWBB1
and /HWBB2), the power supply to the Servomotor will be turned OFF within 8 ms.
