9.2 Register Descriptions.
9.2.14 Register 16-23 - Register no. to place in “Cyclic Read”
These registers contain the numbers that define the registers which are in the Cyclic
Read.
That is the register's, which is transmitted from slave to master cyclically. If some of these
registers are changed, it is necessary to issue a "save in flash" command and to reboot the
device before the changes take effect.
9.2.15 Register 24-31 - Register no. to place in “Cyclic Write”
These registers contain the numbers that define the registers which are in the Cyclic
Write.
That is the register's, which is transmitted from master to slave cyclically. If some of these
registers are changed, it is necessary to issue a "save in flash" command and to reboot the
device before the changes take effect.
9.2.16 Register 32-38
These registers contain HW, SW and communication information of the module.
9.2.17 Register 39 CRC error count on SPI.
This register reflects the no. of CRC errors that have occurred on the internal SPI com-
munication with the motor, since power up.
9.2.18 Register 47 - Digital inputs on module
Only applicable for MAC00-Ex4/-Ex41
With this object the status of the 4 digital inputs can be read.
* The availability of the inputs depends on the actual version of the module used.
MAC00-EC4 only support Input 1 (IN1).
MAC00-EC41 supports input 1, 2, 3 and 4 (IN1, IN2, IN3 and IN4).
9.2.19 Register 48 - Status bits
This register is used for miscellaneous information about the module.
