Automatic shutdown feature
The ACT1000/ACT1000HF has a self-protective shutdown feature. The
ACT1000/ACT1000HF will shut down if:
• Any two motor winding temperatures exceed limit for the given persist time
• Driver board temperature exceeds limit for the given persist time
• There is an EEPROM checksum error during start-up, indicating corrupted parameters on
EEPROM
Note: The POSITION and MOTOR CURRENT feedback signals will be set to 2 mA when
the shutdown alarm is posted.
WARNING
Property damage and injury hazard – If the motor windings exceed 135
C,
the MCE will shut off power to the motor. Touching the
ACT1000/ACT1000HF may result in serious burn injury.
3.8 Changing setup parameters
The ACT1000/ACT1000HF uses a number of variables to define its functionality. These
variables are called Set-Up parameters and they are stored in the MCE EEPROM. Default
values for these variables are loaded into the EEPROM at the PECC factory. The Set-Up
parameters are reloaded into the system registers each time the ACT1000/ACT1000HF is
powered up or reset.
Users can change the Set-Up parameters to better suit their specific applications. These
parameters are uploaded to the ACT1000/ACT1000HF via the RS485 interface using PECC’s
ActWiz software. The Set-Up parameters can only be accessed when the
ACT1000/ACT1000HF is in the Set-Up state. See the basic operation flow chart in Figure 3-1
and the Set-Up State section below for details.
Contact PECC for a copy of ActWiz software. See the ActWiz software manual for further
details.
