These are the contact output signals that output the alarm statuses of this unit. Connect them as
necessary by following the information below.

When an alarm occurs, or L70 (reverse rotation warning)
occurs or a hydraulic switch is actuated, the NO contact opens
(NC contact closes).
The operations vary depending on the values of parameter P39
and P47. See 12.4.

CAUTION
The switching capacity of the contact outputs is DC24 V/1 A (at resistance load). Note that
driving a load exceeding the permissible current may damage the contacts or other
components.
The minimum applicable load for the contact outputs is DC24 V/10 mA (at resistance load), but
this is only a guide to the lower limit where switching is possible with a minute load. The
value varies depending on the switching frequency, environmental conditions, etc., so it is
advisable to check the actual value.
When driving inductive loads, implement surge protection measures.
When an alarm signal is output, take action such as shutting the power off immediately. For
details on handling of alarms, refer to “Chapter 13”.
