#6 (CSA) : The serial pulse coder is defective. Replace it.
#5 (BLA) : The battery voltage is low. Replace the batteries.
#4 (PHA) : The serial pulse coder or feedback cable is defective. Replace the serial
pulse coder or cable.
#3 (PCA) : The serial pulse coder is defective. Replace it.
#2 (BZA) : The pulse coder was supplied with power for the first time.
Make sure that the batteries are connected.
Turn the power off, then turn it on again and perform a reference position
return.
#1 (CKA) : The serial pulse coder is defective. Replace it.
#0 (SPH) : The serial pulse coder or feedback cable is defective. Replace the serial
pulse coder or cable.
