EMERSON A6824 Displacement speed module

The relation between alarm displays and alarm code outputs is shown in Table 10.1. If an alarm occurs, the servomotor can be stopped by doing either of the following operations. • DB STOP: Stops the servomotor immediately using the dynamic brake. • ZERO-SPEED STOP: Stops the servomotor by setting the speed reference to “0.”Regenerative transistor or regenerative resistor is faulty The power supply to the main circuit does not match the parameter Pn001 setting.When the dynamic brake was applied, rotational energy exceeded the capacity of dynamic brake resistor

The alarm meaning differs depending on the SERVOPACK

 capacity. • For the SERVOPACK with a capacity of 5.0 kW or lower: A.40: Overvoltage detection alarm A.41: Undervoltage detection alarm • For the SERVOPACK with a capacity of 6.0 kW or higher: A.40: Alarm detecting excessively high/low voltage in the main circuit A.41: Not used

This warning occurs before the overload alarms (A.71 or A.72) occur. If the warning is ignored and operation continues, an overload alarm may occur. LHH A.92 Regenerative Overload This warning occurs before the regenerative overload alarm (A.32) occurs. If the warning is ignored and operation continues, a regenerative overload alarm may occur. HLH A.93 Absolute Encoder Battery Voltage Lowered This warning occurs when the absolute encoder battery voltage is lowered. If the warning is ignored and operation continues, an overload alarm may occur

Purpose of This Manua

This manual shows you how to use the Very High Speed Counter module with an Allen-Bradley programmable controller. It helps you install, program, and troubleshoot your module. You must be able to program and operate an Allen-Bradley programmable controller (PLC) to make efficient use of this module. In particular, you must know how to program your PLC for block transfer-type instructions. We assume that you know how to do this in this manual. If you do not, refer to the appropriate programming and operations manual for the associated programmable controller before you attempt to use this module
