Assembly Specification
B-1
Basic Speed Control IO (20/70)
Assembly ID 20: Basic
Speed Control Output
Note
For safety reasons, the FWD, REV and RST command operation requires a
rising edge (0 to 1 transition) after power on and fault/trip reset.

Description
FWD
Forward run command
0: Stop
1: Forward run
RST
Fault reset
Reset fault / trip condition on transition from 0 to 1
Rotational
Speed Refer-
ence
Reference rotational speed. Unit: [RPM]/[0.1 Hz]/[0.01 Hz].
If Motor poles setting for RPM (inverter parameter P049 is set to
zero, the Unit depends on the inverter mode (d060):
d060 = 2 (High Frequency mode): Unit is [0.1 Hz]
d060 != 2 (High Frequency mode): Unit is [0.01 Hz]

Speed Monitor
Actual rotational speed monitor. Unit: [RPM]/[0.1 Hz]/[0.01 Hz].
If Motor poles setting for RPM (inverter parameter P049 is set to
zero, the Unit depends on the inverter mode (d060):
d060 = 2 (High Frequency mode): Unit is [0.1 Hz]
d060 != 2 (High Frequency mode): Unit is [0.01 Hz]
