9.1.4  Precautions on Load 
(1) Negative load 
The Servo Amplifier cannot perform such negative load operation as causes the motor to rotate 
continuously. 
 
(Examples) 
•  Downward motor drive (when no counterweight is provided). 
•  Use like a generator, for example, the wind-out spindle of a winder. 
When applying the amplifier to a negative load, consult us. 
 
(2)  Load inertia (JL) 
When the Servo Amplifier is used with a load inertia exceeding the allowable load inertia...

9.1.5  CN1 Input/Output Interface Circuit Configuration 
Input circuit configuration 
(1)  Type 1 (photocoupler input) 
This type of input circuit is a contactless circuit like the one shown on the 
right. 
The input signals of type 1 are Servo ON, alarm reset, forward revolution 
inhibit, backward revolution inhibit, current limit permit deviation clear, 
proportional control, command multiplier, command pulse inhibit (zero 
clamp) and encoder clear (for absolute encoder)....

9－11 
Output circuit configuration 
(1)  Type 6 (open collector output 1) 
This type of output circuit is an isolated contactless circuit like the 
one shown on the right. 
The signals of type 6 are current limit status, low velocity (deviation 
zero), start ready complete, holding brake excitation timing signal 
and alarm code. 
One of the two power supplies of 5 V and 12 V to 24 V can be 
selected (excluding input pins). 
The user must prepare these power supplies.

9.1.6.2  Serial Output (When the ABS-E Absolute Encoder Is Used) 
One of the two position signal outputs can be selected using the remote operator.    When FUNC5 bit 7 on 
Page 6 in Mode 2 of the remote operator is set at 0, start-stop synchronization is selected.     
When bit 6 is set at 1, Manchester coding synchronization is selected.    For details, refer to Func5 in 7.2.3
