Disabling Autorun (for CAN drives); Disabling the setup table at startup (for CAT drives)
3.4.11.1
Disabling Autorun (for CAN drives)
When an iPOS80x0 BX-CAN is set in TMLCAN operation mode, by default after power-on it enters automatically in
Autorun mode. In this mode, if the drive has in its local EEPROM a valid TML application (motion program), this is
automatically executed as soon as the motor supply V
In order to disable Autorun mode, there are 2 methods:
a)
Software - by writing value 0x0001 in first EEPROM location at address 0x4000
b)
Hardware1 – set the drive temporarily in CANopen mode. While in CANopen state, no motion will autorun. Set
SW1 pin1 in down position.
c)
Hardware2 – by temporary connecting all digital Hall inputs to GND, during the power-on for about 1 second,
until the green LED is turned on, as shown in Figure 3.29. This option is particularly useful when it is not
possible to communicate with the drive.
After the drive is set in non-Autorun/slave mode using 2
application from the EEPROM. On next power on, in absence of a valid TML application, the drive enters in the non-
Autorun/slave mode independently of the digital Hall inputs status.
3.4.11.2
Disabling the setup table at startup (for CAT drives)
In some very rare cases, the setup table might be corrupted, leading to a loop where the drive resets continuously. This
behavior can be noticed by seeing both the Ready and Error LED blinking for short periods of time continuously.
To recover from this behavior, the setup table can be invalidated by connecting all digital Hall inputs to GND, as shown
in Figure 3.29.
On the next power on, the drive will load setup default settings and the Motion Error Register (MER) bit 2 will be 1. After
a new valid setup table is loaded onto the drive, disconnect the hall sensors from GND and execute a new power off/
power on cycle.
