1607
Input of motor temperature at which motor must be switched off. The motor temperature is
detected via temperature sensors and evaluated in the drive. The motor is braked in generator
mode when the shutdown limit is reached. A ZK1 message is transmitted to the SERVO (see
also MD 1602 and MD 1603).
Notes:
• The temperature monitoring functions (warning + timer and unconditional shutdown) are
not subject to any mutual restrictions, i.e. MD 1607 may be set lower than MD 1602. In
this case, the motor is switched off without prior warning.
• The motor temperature sensing function is accurate within the 3 - 5 % range.
1608
Input of fixed temperature. If a value higher than 0 is entered, temperature measurement no
longer has any effect. The motor is operated at this fixed temperature.
Note:
The motor temperature monitoring function set in machine data MD 63 is made inoperative if a
fixed temperature is specified.
1610
This machine data can be used to activate diagnostic functions. The function is active when
the appropriate bit is set to 1.
The default setting is dependent on the drive type (FDD ˆ =000, MSD ˆ =001).
Value table:
Bit 0
Bit 1
Bits 2-15
Notes:
• The 611D diagnostic functions are not active in the default setting with the exception of the
dn/dt monitoring function which is always active for MSD drives.
• The monitoring function is not dependent on internal operating modes (feedforward control,
function generator, etc.).
Caution:
This machine data is relevant only for internal Siemens processes and must not be altered.
