1 FUNCTIONS AND CONFIGURATION
1.3 Servo amplifier standard specifications
31
1
*1 0.3 A is the value applicable when all I/O signals are used. The current capacity can be decreased by reducing the number of I/O points.
*2 When closely mounting the servo amplifier, operate it at an ambient temperature of 0

or at 75% or smaller effective load ratio.
*3 Test pulse is a signal which instantaneously turns off a signal to the servo amplifier at a constant period for external circuit to self-
diagnose.
*4 Except for the terminal block.
*5 This value is applicable when a 3-phase power supply is used.
*6 The rated current is 2.9 A when the servo amplifier is used with a UL or CSA compliant servo motor.
*7 When using 1-phase 200 V AC to 240 V AC power supply, operate the servo amplifier at 75% or smaller effective load ratio.
*8 The DC power supply input is available only with MR-J4-_GF-RJ servo amplifiers. For the connection example of the power circuit when
a DC input is used, refer to the following.

*9 Follow the restrictions below when using the servo amplifiers at altitude exceeding 1000 m and up to 2000 m above sea level.
 Page 81 Restrictions when using the servo amplifiers at altitude exceeding 1000 m and up to 2000 m above sea level
*10 The safety level depends on the setting value of [Pr. PF18 STO diagnosis error detection time] and whether STO input diagnosis by
TOFB output is performed or not. For details, refer to the Function column of [Pr. PF18] below.

*11 The MR-J4-_GF servo amplifier is compatible only with the two-wire type. The MR-J4-_GF-RJ servo amplifier is compatible with the two-
wire type, four-wire type, and A/B/Z-phase differential output method.
 Page 18 Summary
*12 The communication cycle depends on the controller specifications and the number of axes connected.
*13 Use an external dynamic brake for this servo amplifier. Failure to do so will cause an accident because the servo motor does not stop
immediately but coasts at emergency stop. Ensure the safety in the entire equipment.
*14 The external dynamic brake cannot be used for compliance with SEMI-F47 standard. Do not assign DB (Dynamic brake interlock) in [Pr.
PD07] to [Pr. PD09]. Doing so will cause the servo amplifier to become servo-off when an instantaneous power failure occurs.
*15 This is used with servo amplifiers with software version A1 or later.
