Mitsubishi FR - S500 instruction manual Second function selection RT signal Setting

1.8 How to Use the Input Signals (Assigned Terminals RL, RM, RH, STR)

These terminals can be changed in function by setting Pr. 60 to Pr. 63.

Pr. 60 "RL terminal function selection" Pr. 61 "RM terminal function selection" Pr. 62 "RH terminal function selection" Pr. 63 "STR terminal function selection"

1.8.1 Multi-speed setting (RL, RM, RH, REX signals): Setting "0, 1, 2, 8" Remote setting (RL, RM, RH signals): Setting "0, 1, 2"

By entering frequency commands into the RL, RM, RH and REX signals and turning on/off the corresponding signals, you can perform multi-speed operation (15 speeds). (For details, refer to page 32.)

If the operation panel is away from the control box, you can perform continuous variable-speed operation with signal contacts, without using analog signals. (For details, refer to page 86.)

1.8.2 Second function selection (RT signal): Setting "3"

Pr. 44 "second acceleration/deceleration time" Pr. 45 "second deceleration time"

Pr. 46 "second torque boost"

Pr. 47 "second V/F (base frequency)"

To set any of the above functions, turn on this "RT signal".

When the 4-20mADC signal is used to perform operation, always short the AU signal.

REMARKS

The current input is ignored if the multi-speed signal is input.

1.8.4 Start self-holding selection (STOP signal): Setting "5"

This connection example is used when you want to self-hold the start signal (forward rotation, reverse rotation).

*Connected to the STOP signal to avoid forward or reverse rotation if forward or reverse rotation and stop are turned on simultaneously.

rotation	STF
