Mitsubishi Electronics FR-S500 instruction manual Multi-speed setting RL, RM, RH, REX signals

How to use the input signals (assigned terminals

RL, RM, RH, STR)

1.5How 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"

Page 98

1.5.1Multi-speed setting (RL, RM, RH, REX signals):

Pr. 60 to Pr. 63 setting "0, 1, 2, 8"

Remote setting (RL, RM, RH signals):

Pr. 60 to Pr. 63 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 29.)

•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 95.)

1.5.2 Second function selection (RT signal): Pr. 60 to Pr. 63 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".

REMARKS

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