Siemens 611 Fixed temperature, Reduce the maximum motor current for safety reasons

Commissioning

9.2 Procedure

5. Fixed temperature

If the temperature monitoring function is not to be evaluated by means of the SME9x and the drive, but externally via the 3RN1013-1GW10 thermistor motor protection instead, monitoring must be deactivated by specifying a fixed temperature > 0.

●MD 1608 = 80, for example = monitoring off

●MD 1608 = 0, for example = monitoring on

6.Reduce the maximum motor current for safety reasons

●MD1105 (maximum motor current) = enter 20%, for example

DANGER

Torque drives can achieve significantly higher rates of acceleration and speeds than conventional drives.

The slewing range must always be kept clear in order to avoid any potential danger for man or machine.

7. Determine the commutation angle offset

The commutation angle offset is determined as follows:

a)Select the identification process using MD 1075. Other machine data may be adapted for the rotor position identification.

b)Save the boot files and perform an NCK reset.

c)Depending on the measuring system used, proceed as follows:
