CHAPTER 4: SETPOINTS CONFIGURATION SETPOINTS
MM200 MOTOR MANAGEMENT SYSTEM – INSTRUCTION MANUAL 4–9
– “MCC Permissive”: This value represents an open contact that disables MCC
control. Used by the auto/manual control element.
– “Remote Reset”: This value represents a contact input used to resets non-lockout
trips and alarms.
– “Reverse Limit”: This value represents a contact which opens at the reverse travel
limit. Used by the reversing starter type.
– “Test Switch”: This value represents a contact input used to suspend collection of
selected data items, override auto/manual modes, and cause interlocks to be
ignored.
– “Power Failure Input”: This value represents a contact input used to detect an
undervoltage which is detected by a digital input associated externally with an
External Voltage Relay and then starts the Power Failure Restart function.
– “Power Failure Restart Inhibit Input”: This value represents a contact input used to
inhibit the Power Failure Restart function.
NOTE
NOTE:
When a Lockout Reset is used to reset a Thermal Overload, the Thermal Capacity % will be
reset to zero.
Outputs
Contact outputs are designated by their card slot letter appended with their card terminal
number. Contact outputs, which have two or three terminals, use the first of their terminal
numbers on the GCP. This is the same scheme as is used to form the relay terminal
designation.
When a starter type is selected, the first equipped contact output and the first equipped
contact input are forced to the contactor A relay function and the contactor A status
function, respectively. When the two-speed or reversing starter type is selected, the
second equipped contact output and the second equipped contact input are forced to the
contactor B relay function and the contactor B status function, respectively. Any prior
values for these setpoints are erased, and the setpoint becomes non-editable.
Communications setpoints
The MM200 has one RS485 serial communications port supporting a subset of the Modbus
protocol. An additional DeviceNet or Profibus port is also available as an option.
The following setpoints are available.
Slave Address
Range: 1 to 254 in steps of 1
Default: 254
For RS485 communications, each MM200 IED must have a unique address from 1 to 254.
Address 0 is the broadcast address detected by all IEDs in the serial link. Addresses do
not have to be sequential, but no two units can have the same address or errors will
occur. Generally, each unit added to the link uses the next higher address starting at 1.
RS485 Baud Rate
Range: 9600, 19200, 38400, 57600, or 115200 baud
Default: 115200 baud
This setpoint selects the baud rate for the RS485 port. The data frame is fixed at 1 start,
8 data, and 1 stop bits, while parity is optional.
