Control Circuit Wiring - Hitachi P1 Basic Instruction Manual

CONTROL CIRCUIT WIRING

Below is a basic example of the control circuit for the Hitachi P1 with the DH firmware and may differ from the actual configuration
please reference the provided electrical drawing. Please consult Detroit Hoist if you plan to make changes to the control circuit for
specific functions to ensure compatibility with the DH firmware. Please note that not all functions provided by standard Hitachi
manual are compatible with the DH firmware and the use of them may cause the VFD to become unusable or unsafe.

24v digital inputs for command functions. 5.6mA
Terminal 4, 6, 8, 9 can be configured for allowed functions.
24v Encoder input for control main body. CA-90 = 02 speed feedback
COM for 24v digital outputs 11 - 15
24v digital outputs. 60mA max
16 relay SPST | 250vac 5A(resistive) \ 250vac 1A(inductive)
Brake release relay SPDT | 250vac 5A(resistive) \ 250vac 1A(inductive)
Analog outputs can be configured for 0-10v or 4-20mA using the dip switches
above.
0v / ground reference for all analog I/O's
Analog inputs, only Ai1 and Ai2 can be configured for 0-10v or 4-20mA.
Ai3 is 0-10v only. Reference the dip switches above the analog terminals for
switching between 0-10v and 4-20mA
Internal 10v reference.
Motor thermistor input. Allowable rated power: 100mW or more
Impedance at abnormal temperature: 3kΩ. DC 0 ~ 5V input circuit. NTC type
recommended in order to use the monitor function for temperature read out.
FM output is selectable from PWM output with a fixed cycle of 6.4ms or pulse
output with a variable cycle. CM1 is COM for FM.
