CONFIGURATION
Changeover Contactor
The relay closes when the high rotor resistance current
ramp has reached full voltage, allowing use with a slip-ring
motor.
Undervoltage
The relay closes when the mains voltage drops below the
level set in parameter 4Q.
Ready
The relay closes when the starter transitions into Ready
mode.
D
Description:
Selects the function of Relay A (normally open).
7B – Relay A On Delay
Range:
0:00 - 5:00 (minutes:seconds)
D
Default:
0 second
Description:
Sets the delay for closing Relay A.
7C – Relay A Off Delay
Range:
0:00 - 5:00 (minutes:seconds)
D
Default:
0 second
Description:
Sets the delay for re-opening Relay A.
7D~7I – Output Relays B and C
Parameters 7D~7I configure the operation of Relays B and C in the same way as parameters 7A~7C
configure Relay A. Refer to Relay A for details.
Relay B is a changeover relay.

7J, 7L – Reserved
These parameters are reserved for future use.
7M – Low Current Flag
The MVS has low and high current flags to give early warning of abnormal operation. The current flags can be
configured to indicate an abnormal current level during operation, between the normal operating level and the
undercurrent or instantaneous overcurrent trip levels. The flags can signal the situation to external equipment via
one of the programmable outputs.
The flags clear when the current returns within the normal operating range by 10% of the programmed
flag value.
Range:
1% - 100% FLC
D
Default:
50%
Description:
Sets the level at which the low current flag operates, as a percentage of motor full load
current.
7N – High Current Flag
Range:
50% - 600% FLC
D
Default:
100%
Description:
Sets the level at which the high current flag operates, as a percentage of motor full load
current.
7O – Motor Temperature Flag
The MVS has a motor temperature flag to give early warning of abnormal operation. The flag can indicate
that the motor is operating above its normal operating temperature but lower than the overload limit. The
flag can signal the situation to external equipment via one of the programmable outputs.
Range:
0% - 160%
D
Default:
80%
Description:
Sets the level at which the motor temperature flag operates, as a percentage of the
motor's thermal capacity.
