Temperature Monitoring
The power-off threshold of the
motor-temperature monitoring
system is fixed for MHD,
MKD, MKE motors.
The following parameters are used to monitor the motor temperature:
Motor warning temperature
Motor shutdown temperature
For MHD, MKD and MKE motors, the parameter default values are fixed
at the following values:
Motor warning temperature = 145.0°C
Motor shutdown temperature = 155.0°C
The drive controller checks for proper functioning of the motor
temperature monitoring system. If discrepancies occur (temperature
drops below –10° Celsius), the warning E221 Warning, Motor temp.
surveillance defective will be displayed for 30 seconds. After that, the
error message F221, Motor temp. surveillance defective is generated.
Load Default
MHD, MKD and MKE motors have data memory circuits in their encoders.
The memory contains a set of default control parameters in addition to all
motor-dependent parameters.
These parameters are activated with “load default.”
5.2 Setting the Motor Type
The setting of the motor type is either:
•
dependent on the motor type used
•
performed automatically by reading the motor feedback memory or
•
via input of parameter CM00, Motor type
The motor type should be set before start-up because the motor type
affects the drive functions.
Automatic Setting of the Motor Type for Motors with Feedback Memory
MHD, MKD and MKE motors have a motor feedback data memory in
which the motor type is stored (along with other information). The drive
controller recognizes these motor types automatically, and the following
actions are taken:
•
The value of parameter CM00, Motor type is set to its proper value
and is write-protected.
•
The value of parameter C001, Interface, encoder 1 is set to the
defined value for the corresponding motor type.
•
All motor-specific parameters are read from the motor feedback
memory.
•
The value for Motor warning temperature is set to 145.0°C and for
Motor shutdown temperature is set to 155.0°C.
•
The value of Parameter CM07, Holding brake type is set to "0". The
value for the Holding brake delay period is set to 150 msec.
This process is executed immediately after the unit is switched on. The
command error message, C204 Motor type incorrect, will be generated
if an MHD, MKD and MKE motor is selected in parameter CM00, Motor
type, but the corresponding character string cannot be found in the motor
feedback data memory.
