R49 (reduced torque) and R48 (torque threshold) are used for the negative direction of rotation.
Digital inputs
The digital inputs are mapped into the status byte in bit
.
Error indication
The terminal offers the user a variety of diagnostic options. These messages are subdivided into hardware
warnings and hardware errors.
Hardware warnings
The functionality of the terminal is retained if one of the following warnings occurs. In the status byte the bit
(Warning) is set.
• Driver in saturation (Saturated
)
◦ This bit is set when the largest duty cycle is output (automatically cancelled)
• Overtemperature (
◦ The status bit is set if the internal terminal temperature exceeds 80 ℃. It is automatically cancelled
if the temperature falls below 80 ℃.
• Overload (overcurrent,
= 0)
◦ This bit is set if the motor current exceeds the value configured in register
◦ This bit is set if the motor current exceeds the value configured in register
when torque limiting is active (
= 1)
• Undervoltage (
◦ This bit is set if the motor voltage falls below 8 V
)
◦ This bit is set if the motor voltage exceeds a value that is 10 % greater than the value configured in
If a warning occurs the cause has to be rectified and subsequently acknowledged and thus cancelled by
setting bit
in the control byte (unless specified otherwise above).
Hardware error
The motor power is switched off and bit
in the status byte is set if one of the following errors
occurs.
• Short Circuit (
• Failure of the 24 V control voltage (No Control Power,
)
◦ This bit is set if the control voltage falls below 12 V (correct function of the driver stages can no
longer be guaranteed if the control voltage is less than 12 V)
◦ The terminal is automatically reinitialized when the control voltage returns
• Other errors (Misc Error,
). The following errors are consolidated through this bit:
◦ Overtemperature (internal terminal temperature exceeds 100 °C, "Overtemperature" bit is also
set),
◦ Initialization error (illogical register configuration)
)
If an error occurs, it first has to be rectified and subsequently acknowledged and thus cancelled by setting bit
