Yaskawa P7B Drive Bypass - Manual (Page 27)

Physical Installation 1 - 15
Drive Multi-function input terminals:
Terminal S
1
receives the Drive run command from the 120 VAC relay logic circuit.
Terminal S
3
receives the Drive run enable signal from the 120 VAC relay logic circuit.
Terminal S
5
receives the Drive local/remote command from the 120 VAC relay logic circuit via the HAND/OFF/
AUTO and NORMAL/TEST selector switch.
Drive Multi-function output terminals:
Terminals M
1
and M
2
are a normally open Drive run relay contact used to communicate the Drive operational mode
to the 120 VAC relay logic circuit.
Terminals M
3
and M
4
are a normally open serial com. run status relay contact used to communicate the Drive
operational state to the 120 VAC relay logic circuit.
Terminals M
A
and M
C
are a normally open Drive fault relay contact used to communicate the Drive fault status to the
120 VAC relay logic circuit.
" PCB Jumpers explained
The S101 “Berg pin” jumper on the control relay logic PCB A2 is not for field use. It is employed only in the factory to enable
the 2 motor “OR” configured option. It is removed when this option is present and must be in place when this option is not part
of the unit specification (See Figure 1.9).
The S102 “Berg pin” jumper on the control relay logic PCB A2 is not for field use. It is employed only in the factory to enable
the Run/Stop Push Button (3 wire control) configured option. It is removed when this option is present and must be in place
when this option is not part of the unit specification (See Figure 1.9).
TB1 terminals 1 and 2 are jumpered (J1) as the unit is shipped from the factory. If a customer supplied series circuit of NC
safety devices is to be used, this jumper is removed and the safety circuit connected between terminals 1 and 2.
TB1 terminals 5 and 6 are jumpered (J2) as the unit is shipped from the factory. If a customer supplied Drive NO enabling
contacts are to be used (such as a damper end switch or occupied cycle timer), this jumper is removed and the enabling
contacts wired between terminals 5 and 6.
