Multi-Step Speed Command - Hitachi P1 Basic Instruction Manual

MULTI-STEP SPEED COMMAND

Multi-Step speed command can be configured up to 16 speeds. Only use multi-step speed command when speed control greater than
3-steps is required. In the multi-step speed command, 4 inputs as a binary combination of 0 (OFF) and 1 (ON) will determine the
command frequency, reference the chart below for configuring the steps and speeds. Use the chart below to configure the use of the
multi-step speed command.
NOTE – The multi-step speed command steps outside of the internal program to determine the speeds during normal operation.
Please make sure that Ab110 & UE-11 match for the low frequency value. Also make sure to set UE-12 to match the high-speed
frequency determined by the multi-speed binary operation.
