Cables for Linear Servomotors
Connections to Linear Encoders from Mitutoyo Corporation
• ST78A/ST13 Linear Encoders
Important
1. You cannot use a ST78A Linear Encoder together with a Linear Servomotor with a Polarity
Sensor.
2. If you use an SGLFW2 Servomotor, input the thermal protector signal from the Linear Servomotor
to the host controller. The thermal protector signal is closed when the temperature is
normal and open when the thermal protector is activated. Do not exceed 3 A or 30 V.
