Acceleration Time Scale
AccelUnits.TimeScale
This parameter is the time units for accel./decel. ramps. Possible selections are milliseconds or seconds.
At Velocity
AtVel
This source is active when EZMotion is executing a constant velocity motion segment. One example would be during an
index. The source would activate after the motor has finished accelerating up to speed and before the motor begins to
decelerate to a stop. A normal index consists of 3 segments: Accelerating, At Velocity, and Decelerating. This source is active
during the At Velocity segment, and is activated based on the commanded velocity, not the feedback velocity. During
synchronized motion, AtVel can be active without actual motor movement.
Bit Number Value
Bit.B# or Bit.BitName
This read/write bit may be used in a program as an intermediary variable bit controlled by the user. Bit.B# is one of 32 bits that
make up the BitRegister parameter. Assigned to communication networks such as DeviceNet, Profibus and Modbus, Bit.B#
may be used to transfer events that have occurred in a PLC to the EZMotion program.
NOTE
When the value of Bit.B# is changed, the value of BitRegister.#.Value is changed as well.
Bit Register Number Value
BitRegister.#.Value
This parameter is made up of the combination of the 32 Bit.B#. The BitRegister.#.Value. The BitRegister.#.Value register may
be accessed bitwise by using Bit.B#, or double word-wise by using BitRegister.#.Value.
Bit Register Number Value Mask
BitRegister.#.ValueMask
This parameter is the Mask for the BitRegister.#.Value. Each bit location is set to either transfer the current data in the
corresponding bit location of BitRegister.#.Value (by setting the bit location to 1) or to clear the current data in
BitRegister.#.Value (by setting the bit location to 0).
Braking Resistor Overload Accumulator
BrakeOverloadAccumulator
This parameter gives an indication of braking resistor temperature based on a simple thermal model. The formula for the
thermal model is a function of parameters 10.30 and 10.31 (set in the initialization file). A value of zero indicates that the
resistor is close to ambient, and a value of 100% is the maximum temperature (trip level). An OVLd warning is given if this
parameter is above 75% and the braking IGBT is active. This parameter can be found on the Online tabs of the Status and
Current views.
Braking Resistor Alarm
BrakeResistorAlarm
This parameter is set when the braking IGBT is active and the braking overload accumulator is greater than 75%. This
parameter when activated is automatically kept active for 0.5 seconds so that it can be displayed on the keypad display. This
parameter can be found on the Online tabs of the Status and Current views.
Bus Voltage
BusVoltage
This read-only parameter displays the instantaneous voltage value of the DC bus in the drive. This parameter is found on the
Status Online tab on the Status view and is read directly from parameter 5.05 in the database.
Active Point
Cam.ActivePoint
This parameter is the point within a cam table that is being executed. This is useful to determine the cam location when a fault
occurs. This only available when online.
